> I tried to run tpcds_sf100-query2 on parquet table in 10 concurrency threads on single node drillbit cluster (I use Drill with DRILL-5599 fix) and caught a resources leak. The query hanged in CANCELLATION_REQUESTED state.
> Steps to reproduce:
> 1) Start ConcurrencyTest.java with tpcds_sf100-query2 on parquet table (in attachment);
> 2) Wait 3-5 seconds and make Ctrl+c to kill a client.
> 3) Retry step 2) several times until you get "CANCELLATION_REQUESTED" on some queries.
> Queries will hang until drillbit restart. If we make "top", we can see that drillbit uses CPU.
> Jstack example:
> {code:xml}
