-------------------------------------------
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.
