------------------------------------------------
Summary: Foreman node is going down when the non foreman node is
stopped
Key: DRILL-6252
URL: https://issues.apache.org/jira/browse/DRILL-6252
Project: Apache Drill
Issue Type: Bug
Reporter: Venkata Jyothsna Donapati
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
