Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

-# Quick Start(run griffin data quality in spark cluster)
-
-## Environment Preparation
-Prepare the environment for Apache Griffin. 
-You can use our pre-built docker images as the environment.
-Follow the [docker guide](https://github.com/apache/incubator-griffin/blob/master/griffin-doc/docker/griffin-docker-guide.md#environment-preparation) to start up the docker images, and login to the griffin container.
-```
-docker exec -it <griffin docker container id> bash
-cd ~/measure
-```
-
-## Data Preparation
-Prepare the test data in Hive.
-In the docker image, we've prepared two Hive tables named `demo_src` and `demo_tgt`, and the test data is generated hourly.
-The schema is like this:
-```
-id                      bigint                                      
-age                     int                                         
-desc                    string                                      
-dt                      string                                      
-hour                    string 
-```
-In which `dt` and `hour` are the partition columns, with string values like `20180912` and `06`.
-
-## Configuration Files
-The environment config file: env.json
-```
-{
-  "spark": {
-    "log.level": "WARN"
-  },
-  "sinks": [
-    {
-      "type": "console"
-    },

-        "method": "post",
-        "api": "http://es:9200/griffin/accuracy"
-      }
-    }
-  ]
-}
-```
-The DQ config file: dq.json
-```
-{
-  "name": "batch_accu",
-  "process.type": "batch",
-  "data.sources": [
-    {
-      "name": "src",
-      "baseline": true,

-            "table.name": "demo_tgt"
-          }
-        }
-      ]
-    }
-  ],

-    "rules": [
-      {
-        "dsl.type": "griffin-dsl",
-        "dq.type": "accuracy",
-        "out.dataframe.name": "accu",
-        "rule": "src.id = tgt.id AND src.age = tgt.age AND src.desc = tgt.desc",
-        "details": {
-          "source": "src",
-          "target": "tgt",
-          "miss": "miss_count",
-          "total": "total_count",
-          "matched": "matched_count"
-        },
-        "out": [
-          {
-            "type": "metric",
-            "name": "accu"
-          },
-          {
-            "type": "record",
-            "name": "missRecords"
-          }
-        ]
-      }
-    ]
-  },
-  "sinks": ["CONSOLE", "HDFS"]
-}
-```
-
-## Submit Measure Job
-Submit the measure job to Spark, with config file paths as parameters.
-```
-spark-submit --class org.apache.griffin.measure.Application --master yarn --deploy-mode client --queue default \
---driver-memory 1g --executor-memory 1g --num-executors 2 \
-<path>/griffin-measure.jar \
-<path>/env.json <path>/batch-accu-config.json
-```
-Then you can get the calculation log in console, after the job finishes, you can get the result metrics printed. The metrics will also be saved in hdfs: `hdfs:///griffin/persist/<job name>/<timestamp>/_METRICS`.
-
-## More Details
-For more details about griffin measures, you can visit our documents in [github](https://github.com/apache/incubator-griffin/tree/master/griffin-doc).
