[GitHub] [samza] prateekm opened a new pull request #1257: SAMZA-2443: Upgrade Jetty version to prevent AM file descriptor leak

prateekm opened a new pull request #1257: SAMZA-2443: Upgrade Jetty version to prevent AM file descriptor leak
URL: https://github.com/apache/samza/pull/1257
 
 
   Symptom: AM Process runs out of file descriptors and gets stuck during deployment of jobs with a large number of containers. Containers are unable to start since they can’t fetch the JobModel and configs from the AM endpoint.
   
   Cause: This seems to be a Jetty bug that’s fixed in the latest versions. For more details, see: https://docs.google.com/document/d/1RFf_3_lJHHdoZHQlikSDHcm55GYbp7ObA8qVUwr-6p0/edit#
   
   Changes: Bump Jetty version to 9.4.20.v20190813
   
   Tests: Reproduced locally using the test harness in https://github.com/prateekm/samza/commit/6d7e01b5b9d0d38a7766357a870ba7daeadd828e. All unit and integration tests pass with the version bump. Verified that Samza jobs are able to deploy correctly on a YARN cluster with the version bump.
   
   API Changes: Jetty version upgraded from 9.2.7.v20150116 to 9.4.20.v20190813.
   
   Upgrade Instructions: None.
    
   Usage Instructions: None.
