Mridul Muralidharan created SPARK-25594:
-------------------------------------------

             Summary: OOM in long running applications even with UI disabled
                 Key: SPARK-25594
                 URL: https://issues.apache.org/jira/browse/SPARK-25594
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.3.0, 2.4.0
            Reporter: Mridul Muralidharan
            Assignee: Mridul Muralidharan


Typically for long running applications with large number of tasks it is common to disable UI to minimize overhead at driver.
Earlier, with spark ui disabled, only stage/job information was kept as part of JobProgressListener.

As part of history server scalability fixes, particularly SPARK-20643, inspite of disabling UI - task information continues to be maintained in memory.
In our long running tests against spark thrift server, this eventually results in OOM.
