----------------------------------
Summary: thrift server memory leak when beeline connection quits
Key: SPARK-24629
URL: https://issues.apache.org/jira/browse/SPARK-24629
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.3.1, 2.2.1
Reporter: StephenZou
When Beeline connection closes, spark thrift server (STS) will send a session
close event, then the relevant listener in class HiveThriftServer2 will clean
its internal session states.
But the internal statement state is not updated, (see graph attached). So it
remains in state Compiled and doesn't be swept out.
