[LIVY-714][SERVER] Fix cannot remove the app in leakedAppTags when timeout ## What changes were proposed in this pull request? 1.`var isRemoved = false` should be in `while(iter.hasNext),` otherwise if there are two apps, the first app will be killApplication and the second app will timeout in this loop, and after removing the first app,` isRemoved = true`, and the second app cannot pass the` if(!isRemoved)` and only will be deleted in the next loop. 2.`entry.getValue - now` is negative, and never greater than `sessionLeakageCheckTimeout`. ![image](https://user-images.githubusercontent.com/51938049/69202431-99a81080-0b7c-11ea-8084-9801af5a75bd.png) ## How was this patch tested? Existed IT and UT. Author: runzhiwang <runzhiwang@tencent.com> Closes #259 from runzhiwang/leakapp.
Apache Livy is an open source REST interface for interacting with Apache Spark from anywhere. It supports executing snippets of code or programs in a Spark context that runs locally or in Apache Hadoop YARN.
Pull requests are welcomed! But before you begin, please check out the Contributing section on the Community page of our website.
Guides and documentation on getting started using Livy, example code snippets, and Livy API documentation can be found at livy.incubator.apache.org.
To build Livy, you will need:
Debian/Ubuntu:
maven
package or maven3 tarball)Redhat/CentOS:
maven
package or maven3 tarball)MacOS:
Required python packages for building Livy:
To run Livy, you will also need a Spark installation. You can get Spark releases at https://spark.apache.org/downloads.html.
Livy requires Spark 2.2+. You can switch to a different version of Spark by setting the SPARK_HOME
environment variable in the Livy server process, without needing to rebuild Livy.
Livy is built using Apache Maven. To check out and build Livy, run:
git clone https://github.com/apache/incubator-livy.git cd incubator-livy mvn package
By default Livy is built against Apache Spark 2.2.0, but the version of Spark used when running Livy does not need to match the version used to build Livy. Livy internally handles the differences between different Spark versions.
The Livy package itself does not contain a Spark distribution. It will work with any supported version of Spark without needing to rebuild.
