Eric Payne commented on YARN-9931:
----------------------------------
YARN allows the owner of the application (or a cluster admin) to dump the
jstack of the container, either from the command line or from CLI, using
https://hadoop.apache.org/docs/r3.1.0/api/org/apache/hadoop/yarn/api/records/SignalContainerCommand.html
>From command line, for example, the following will put a stack trace in the
>stdout of the container's logs:
{code}
yarn container -signal container_1466534149943_0002_01_000007OUTPUT_THREAD_DUMP
{code}
After that, the container can be killed.
Will this suit your use caes?

> Like node health check script. We can add a pre-kill script which run before

> For example we can save the thread dump before kill the container, which is
