Pengcheng Xiong commented on HIVE-16136:
----------------------------------------
I am deferring this to Hive 3.0 as we are going to cut the first RC and it is
not marked as blocker. Please feel free to commit to the branch if this can be
resolved before the release.
> LLAP: Before SIGKILL, 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.
> There is no clean way to trap SIGKILL in java.
> One option is to increase the time between kill and kill -9 in YARN and
> during that time we can have a shutdown hook handler to collect all
> diagnostics information like heapdump, jstack, jmx output etc. in a
> non-container directory.
