[jira] [Created] (KYLIN-967) Dump running queries on memory shortage

liyang created KYLIN-967:
----------------------------

             Summary: Dump running queries on memory shortage
                 Key: KYLIN-967
                 URL: https://issues.apache.org/jira/browse/KYLIN-967
             Project: Kylin
          Issue Type: Bug
            Reporter: liyang


Encountered high GC in Kylin query service sometimes. Suspect some bad query is taking up too much system resource.

The feature should dump running queries on resource shortage. Then troubleshoot can proceed. Optionally, bad query can be killed once detected.
