> spark thrift server driver memory leak
> --------------------------------------

> Reporter: wangdabin
> Priority: Major
>
> When using the spark thrift server, the driver memory is getting bigger and

> that the SparkSQLOpeartionManager handleToOperation object is not released,
> resulting in memory leaks, and the final result is service downtime.
