> Two drillbits are running. I'm running a join query over parquet and tried to
> stop the non-foreman node using drillbit.sh stop. The query fails with
> *"Error: DATA_READ ERROR: Exception occurred while reading from disk".* The
> non-foreman node goes down. The foreman node also goes down. When I looked at
> the drillbit.log of both foreman and non-foreman I found that there is memory
> leak "Memory was leaked by query. Memory leaked:
> (2097152)\nAllocator(op:2:0:0:HashPartitionSender)
> 1000000/6291456/6832128/10000000000 (res/actual/peak/limit)\n". Following are
> the stack traces for memory leaks
