> thrift server memory leak when beeline connection quits
> -------------------------------------------------------
>
> Key: SPARK-24629

> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.1, 2.3.1

>
> 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.
