> DrillBit is un-responsive after a query with multiple joins is executed
> repeatedly
> ----------------------------------------------------------------------------------
>
> Key: DRILL-544
> URL: https://issues.apache.org/jira/browse/DRILL-544
> Project: Apache Drill
> Issue Type: Bug
> Environment: Centos 6.4
> 96GB RAM
> Reporter: Kunal Khatua
>
> When running a query against a standalone DrillBit with default settings,
> every run of a query with joins results in the memory for the DrillBit
> process increasing. This occurs, irrespective of whether the query runs to
> completion or not.
> After a number of runs, the DrillBit becomes unresponsive, with no CPU
> activity visible with the top command.
