             Summary: LLAP: Trap SIGKILL and collect diagnostic information before daemon goes down
                 Key: HIVE-16136
                 URL: https://issues.apache.org/jira/browse/HIVE-16136
             Project: Hive
          Issue Type: Bug
          Components: llap
    Affects Versions: 2.2.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran


Sometime daemons can get killed by YARN's pmem monitor which issue a kill followed by kill -9 after 250ms. This is really a short duration to collect anything useful. One option is to optionally trap SIGKILL requests and collect all diagnostics information like heapdump, jstack, jmx output etc. in a non-container directory.
