[GitHub] [hive] rbalamohan opened a new pull request #1921: HIVE-24695: Clean up session resources, if TezSession is unable to start
rbalamohan opened a new pull request #1921:
URL: https://github.com/apache/hive/pull/1921
https://issues.apache.org/jira/browse/HIVE-24695
### What changes were proposed in this pull request?
There are cases when TezSessionState would not be able to start. (e.g resource constraints on YARN queues).
However by this time, session directories & certain resources are localized. (e.g, hive-exec jars are stored in hdfs:///tmp/hive/hive/_tez_session_dir//hive-exec.jar). When tezClient is not started, it does not clear up the resources. This leaks ~100MB data in HDFS per failure.
### Why are the changes needed?
Need to clear up resources in session directory, when errors are encountered in tez session init phase.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Small scale cluster
