Work Description: mustafaiman opened a new pull request #1235:
URL: https://github.com/apache/hive/pull/1235
Each query creates a shutdownRunner which will release transactional
resources in case JVM exits mid-query. These shutdownRunners are not removed
until session is closed. Session lifetime is unbounded. These shutdown hooks
can cause OOM. We should remove them once query is committed or rolled back.

> Each query registers a shutdownHook to release transactional resources in
> case JVM shuts down mid query. These hooks are not cleaned up until session
> is closed. Session life time is unbounded. So these hooks are a memory leak.
> They should be cleaned as soon as transaction is completed.
