> 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.
