-# How to adapt Linkis with a new computation or storage engine
-
-## 1. Introduction
-
-Except using the engines developed by Linkis directly, backend developers can also develop their own applications based on their requirements. 
-Divided into Entrance, EngineManager and Engine modules, one can easily split an application to adapt to Linkis. 
-The purpose and archetecture of these three modules please refer to Linkis Archetect Design Docs[UJES架构设计文档](../ch4/Linkis-UJES设计文档.md).
-
-
-## 2. Declaration
-
-Linkis uses Spring framework as the underlying technique. So the Spring development specs must be obeyed.
-
-Linkis has an elastic underlying achitecture and provides common implementations for almost all of its top-level interfaces. If customized classes are needed by users, they can be directly injected and replace the current implementations.
-
-
-### 2.1 Entrance module adaption
-
-**1) maven dependency**
-
-```xml
-<dependency>
-  <groupId>com.webank.wedatasphere.Linkis</groupId>
-  <artifactId>Linkis-ujes-entrance</artifactId>
-  <version>0.9.3</version>
-</dependency>
-```
-
-**2)Interfaces to be implemented**
-
-There is no compulsary interface in Entrance. Below interfaces can be implemented on demand.
-- EntranceParser. Used to parse request maps from frontend to a persistable Task. Class AbstractEntranceParser is already provided and only parseToTask method needs to be overrided. Linkis provides CommonEntranceParser as the default implementation.
-- EngineRequester. Used to build a RequestEngine object, which can be used to request a new engine from the EngineManager.
-- Scheduler. Used to schedule tasks. The default implementation provides parallel mode for multi-user situations and FIFO mode for single user pattern. It is not suggested to be customized without special purposes.
-
-### 2.2 EngineManager module adaption
-
-**1) maven dependency**
-
-```xml

-  <groupId>com.webank.wedatasphere.Linkis</groupId>
-  <artifactId>Linkis-ujes-enginemanager</artifactId>
-  <version>0.9.3</version>
-</dependency>
-```
-
-**2)Interfaces to be implemented**
-
-Below interfaces are required to be implemented in EngineManager:
-- EngineCreator. Method createProcessEngineBuilder needs to be overridden in the existing AbstractEngineCreator to create an EngineBuilder.
-Here ProcessEngineBuilder has already provided a class called JavaProcessEngineBuilder, which is an abstract class accomplishes configurations of classpath, JavaOpts, GC file path and log path, and opening DEBUG port in test mode. To implement JavaProcessEngineBuilder, only extra classpath and JavaOpts are needed to be specified.
-- EngineResourceFactory. Method getRequestResource needs to be overridden in the existing AbstractEngineResourceFactory to declare user customized resource requirements.
-- resources. A Spring bean used to register resources to RM. Users need to specify an instance of ModuleInfo for dependency injection.
-
-Below interfaces/beans are optional in EngineManager:
-- hooks. A Spring bean used to add pre and post hooks around the Engine startup procedure. Users need to declare an Spring bean in type EngineHook[] hooks to make new hooks effective. For details please refer to com.webank.wedatasphere.linkis.enginemanager.impl.EngineManagerSpringConfiguration.
-
-
-### 2.3 Engine module adaption

-
-
-**2)Interfaces to be implemented**
-
-Below interfaces are required to be implemented in Engine：
-- EngineExecutorFactory. Used to build an EngineExecutor from a Map by implementing method createExecutor. This map contains evironment variables and engine arguments.
-- EngineExecutor. The actual executor to execute the code submitted from the entrance. 
-    Methods need to be implemented: 
-      1. getActualUsedResources(the resource an engine acually used)
-      2. executeLine(execute a line of the code parsed by CodeParser)
-      3. executeCompletely(the suplementary method for executeLine. If executeLine returns ExecuteIncomplete, new code will be submitted with the previous code together to the engine)
-
-Below interfaces/beans are optional in Engine:
-- engineHooks: Array[EngineHook], a Spring bean used to add pre and post hooks around the Engine startup procedure. Currently the system provides 2 hooks: CodeGeneratorEngineHook for UDF/Function loading and ReleaseEngineHook for releasing spare engines. The system registers engineHooks=Array(ReleaseEngineHook) only by default.
-- CodeParser. Used to parse code into lines and submit one line only for each execution loop. The system registers a CodeParser returns all the code at once by default. 
-- EngineParser. Used to convert a RequestTask to a Job that is acceptable by Scheduler. If not specified, the system registers an EngineParser that converts RequestTask to CommonEngineJob.

-## Linkis User Manual
-
-#### 1.Summary
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Designed by Webank independently, Linkis is an extensible framework and a sophisticated solution for big data task submission. Conveniently, it could be used directly together with Scriptest, which is another open-source project powered by Webank. And those frontend APIs are also available for users. A client implementation is also provided as an SDK to interact directly with background services. As an highly extensible framework, users can leverage the SDK to develop their own applications.
-
-#### 2.Frontend Adaption
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Two protocols are supported for frontend APIs: HTTP and WebSocket. Compared with HTTP, Websocket is more friendly to servers and behaved more efficiently in message pushing. But WebSocket is unstable and users are easily to be disconnected by accident. So Scriptest combined both ways to adapt with Linkis. It communicates with Linkis by websocket in normal circumstances, and failover to HTTP protocol in case the Websocket connection was down.

-### 3.Client SDK Adaption
-[Please see Linkis Quick Start](/docs/en_US/ch2/Linkis%20Quick%20Start.md)
-
-
-
-#### 4. Multiple engine type support
-Except using the engines developed by Linkis directly, backend developers can also develop their own applications based on their requirements. Divided into Entrance, EngineManager and Engine modules, one can easily split an application to adapt to Linkis. The purpose and architecture of these three modules please refer to Linkis Architect Design Docs.
-
-#### Convention
-
-Linkis uses Spring framework as the underlying technique. So instances of some classes can be injected using Spring annotations. Linkis provides some default common implementations. If customized classes are needed by users, they can be directly injected and replace the current implementations.
-
-##### 4.1Entrance module adaption
-**1)maven dependency**
-```xml
-<dependency>
-  <groupId>com.webank.wedatasphere.linkis</groupId>
-  <artifactId>linkis-ujes-entrance</artifactId>
-  <version>0.9.3</version>
-</dependency>
-```
-**2)Interfaces to be implemented**
-
-There is no compulsory interface in Entrance. Below interfaces can be implemented on demand.
-- EntranceParser. Used to parse request maps from frontend to a persistable Task. Class AbstractEntranceParser is already provided and only parseToTask method needs to be overridden. Linkis provides CommonEntranceParser as the default implementation.
-- EngineRequester. Used to build a RequestEngine object, which can be used to request a new engine from the EngineManager.
-- Scheduler. Used to schedule tasks. The default implementation provides parallel mode for multi-user situations and FIFO mode for single user pattern. It is not suggested to be customized without special purposes.
-
-##### 4.2EngineManager module adaption
-**1)maven dependency**
-```xml
-<dependency>
-  <groupId>com.webank.wedatasphere.linkis</groupId>
-  <artifactId>linkis-ujes-enginemanager</artifactId>
-  <version>0.9.3</version>
-</dependency>
-```
-
-**2)Interfaces to be implemented**
-
-Below interfaces are required to be implemented in EngineManager:
-- EngineCreator. Method createProcessEngineBuilder needs to be overridden in the existing AbstractEngineCreator to create an EngineBuilder.
-Here ProcessEngineBuilder has already provided a class called JavaProcessEngineBuilder, which is an abstract class accomplishes configurations of classpath, JavaOpts, GC file path and log path, and opening DEBUG port in test mode. To implement JavaProcessEngineBuilder, only extra classpath and JavaOpts are needed to be specified.
-- EngineResourceFactory. Method getRequestResource needs to be overridden in the existing AbstractEngineResourceFactory to declare user customized resource requirements.
-- hooks. A Spring bean used to add pre and post hooks around the Engine startup procedure. Users need to specify an Array[EngineHook] for dependency injection.
-- resources. A Spring bean used to register resources to RM. Users need to specify an instance of ModuleInfo for dependency injection.
-
-##### 4.3Engine module adaption
-**1)maven dependency**
-```xml
-<dependency>
-  <groupId>com.webank.wedatasphere.linkis</groupId>
-  <artifactId>linkis-ujes-engine</artifactId>
-  <version>0.9.3</version>
-</dependency>
-```
-**2)Interfaces to be implemented**
-
-Below interfaces are required to be implemented in Engine：
-- EngineExecutorFactory. Used to build an EngineExecutor from a Map by implementing method createExecutor.
-- EngineExecutor. The actual executor to execute the code submitted from the entrance. Methods need to be implemented: getActualUsedResources(the resource an engine acually used), executeLine(execute a line of the code parsed by CodeParser), executeCompletely(the suplementary method for executeLine. If executeLine returns ExecuteIncomplete, new code will be submitted with the previous code together to the engine)
-
-Below interfaces/beans are optional in Engine:
-- engineHooks: Array[EngineHook], a Spring bean used to add pre and post hooks around the Engine startup procedure. Currently the system provides 2 hooks: CodeGeneratorEngineHook for UDF/Function loading and ReleaseEngineHook for releasing spare engines. The system registers engineHooks=Array(ReleaseEngineHook) only by default.
-- CodeParser. Used to parse code into lines and submit one line only for each execution loop. The system registers a CodeParser returns all the code at once by default. 
+## Linkis User Manual
+
+#### 1.Summary
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Designed by Webank independently, Linkis is an extensible framework and a sophisticated solution for big data task submission. Conveniently, it could be used directly together with Scriptest, which is another open-source project powered by Webank. And those frontend APIs are also available for users. A client implementation is also provided as an SDK to interact directly with background services. As an highly extensible framework, users can leverage the SDK to develop their own applications.
+
+#### 2.Frontend Adaption
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Two protocols are supported for frontend APIs: HTTP and WebSocket. Compared with HTTP, Websocket is more friendly to servers and behaved more efficiently in message pushing. But WebSocket is unstable and users are easily to be disconnected by accident. So Scriptest combined both ways to adapt with Linkis. It communicates with Linkis by websocket in normal circumstances, and failover to HTTP protocol in case the Websocket connection was down.

+  <version>0.9.4</version>
+</dependency>
+```
+**2)Interfaces to be implemented**
+
+There is no compulsory interface in Entrance. Below interfaces can be implemented on demand.
+- EntranceParser. Used to parse request maps from frontend to a persistable Task. Class AbstractEntranceParser is already provided and only parseToTask method needs to be overridden. Linkis provides CommonEntranceParser as the default implementation.
+- EngineRequester. Used to build a RequestEngine object, which can be used to request a new engine from the EngineManager.
+- Scheduler. Used to schedule tasks. The default implementation provides parallel mode for multi-user situations and FIFO mode for single user pattern. It is not suggested to be customized without special purposes.
+
+##### 4.2EngineManager module adaption
+**1)maven dependency**
+```xml
+<dependency>
+  <groupId>com.webank.wedatasphere.linkis</groupId>
+  <artifactId>linkis-ujes-enginemanager</artifactId>
+  <version>0.9.4</version>
+</dependency>
+```
+
+**2)Interfaces to be implemented**
+
+Below interfaces are required to be implemented in EngineManager:
+- EngineCreator. Method createProcessEngineBuilder needs to be overridden in the existing AbstractEngineCreator to create an EngineBuilder.
+Here ProcessEngineBuilder has already provided a class called JavaProcessEngineBuilder, which is an abstract class accomplishes configurations of classpath, JavaOpts, GC file path and log path, and opening DEBUG port in test mode. To implement JavaProcessEngineBuilder, only extra classpath and JavaOpts are needed to be specified.
+- EngineResourceFactory. Method getRequestResource needs to be overridden in the existing AbstractEngineResourceFactory to declare user customized resource requirements.
+- hooks. A Spring bean used to add pre and post hooks around the Engine startup procedure. Users need to specify an Array[EngineHook] for dependency injection.
+- resources. A Spring bean used to register resources to RM. Users need to specify an instance of ModuleInfo for dependency injection.
+
+##### 4.3Engine module adaption
+**1)maven dependency**
+```xml
+<dependency>
+  <groupId>com.webank.wedatasphere.linkis</groupId>
+  <artifactId>linkis-ujes-engine</artifactId>
+  <version>0.9.4</version>
+</dependency>
+```
+**2)Interfaces to be implemented**
+
+Below interfaces are required to be implemented in Engine：
+- EngineExecutorFactory. Used to build an EngineExecutor from a Map by implementing method createExecutor.
+- EngineExecutor. The actual executor to execute the code submitted from the entrance. Methods need to be implemented: getActualUsedResources(the resource an engine acually used), executeLine(execute a line of the code parsed by CodeParser), executeCompletely(the suplementary method for executeLine. If executeLine returns ExecuteIncomplete, new code will be submitted with the previous code together to the engine)
+
+Below interfaces/beans are optional in Engine:
+- engineHooks: Array[EngineHook], a Spring bean used to add pre and post hooks around the Engine startup procedure. Currently the system provides 2 hooks: CodeGeneratorEngineHook for UDF/Function loading and ReleaseEngineHook for releasing spare engines. The system registers engineHooks=Array(ReleaseEngineHook) only by default.
+- CodeParser. Used to parse code into lines and submit one line only for each execution loop. The system registers a CodeParser returns all the code at once by default. 
 - EngineParser. Used to convert a RequestTask to a Job that is acceptable by Scheduler. If not specified, the system registers an EngineParser that converts RequestTask to CommonEngineJob.

-### Linkis Java SDK Doc
-#### 1.Introduction
-
-Linkis provides a Java client implementation for users to have quick-access to Linkis background services using UJESClient.
-
-#### 2 Quick start
-
-   We provided two test classes under dir ujes/client/src/test：
-        
-        com.webank.wedatasphere.linkis.ujes.client.UJESClientImplTestJ # Test class based on Java
-        com.webank.wedatasphere.linkis.ujes.client.UJESClientImplTest # Test class based on Scala
-
-   If you have cloned the source code of Linkis, you can directly run these two test classes.
-
-
-   **Below sections introduce about how to write the code to complete a single execution on Linkis**
-
-#### 3 Fast implementation
