> 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.
