StephenZou updated SPARK-24629:
-------------------------------
Description:
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.
Another graph is that after fixing it.
