> do you have a use case which could not be handled by those?
The oom hook holds a hiveserver2 instance, which calls hiveserver2::stop()
to end hiveserver2 gracefully, which would cleanup the session
directory/scratch directory/operation log and so on . Although the hooks in the
driver can handle oom, he may not be able to stop the hiveserver2 gracefully as
the oom hook does. Sometimes we may want to dump the heap for futher analysis
when oom happens or alter the devops, so it may be better to make the oom hook
here an interface.
