Khurram Faraaz created DRILL-6247:
-------------------------------------
Summary: Minor fragments remain in CANCELLATION_REQUESTED state
after query failure
Key: DRILL-6247
URL: https://issues.apache.org/jira/browse/DRILL-6247
Project: Apache Drill
Issue Type: Bug
Components: Execution - Flow
Affects Versions: 1.13.0
Reporter: Khurram Faraaz
Attachments: cancellation_requested_march_14.png,
drillbit_snippet.log, jstack_cancellation_requested.txt
Once a query fails, in this case due to an OOM in RPC we see many minor
fragments are reported to be in CANCELLATION_REQUESTED state on Web UI after
query has failed. The problem is reproducible. drillbit.log for this failure
and jstack output are attached here.
To reproduce the problem on a 4 node cluster.
alter system reset all;
alter system set `planner.slice_target`=1;
Failing query => SELECT * , FLATTEN(arr) FROM many_json_files;
Drill 1.13.0-SNAPSHOT, commit id: 766315ea17377199897d685ab801edd38394fe01
