Date Sun, 14 Feb 2016 05:45:18 GMT
Shinichi Yamashita created HIVE-13058:
-----------------------------------------

             Summary: Add session and operation_log directory deletion messages
                 Key: HIVE-13058
                 URL: https://issues.apache.org/jira/browse/HIVE-13058
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
            Reporter: Shinichi Yamashita
            Assignee: Vaibhav Gumashta
            Priority: Minor


In the current master, when connecting to HS2, we can confirm that some directories were created.
For example the following messages of HS2 log.

{code}
2016-02-14T13:57:52,412 INFO  [HiveServer2-Handler-Pool: Thread-607]: session.SessionState
(SessionState.java:createPath(693)) - Created HDFS directory: /tmp/hive/root/bfe28a51-5804-4cbb-952c-26709aed4652
2016-02-14T13:57:52,416 INFO  [HiveServer2-Handler-Pool: Thread-607]: session.SessionState

2016-02-14T13:57:52,421 INFO  [HiveServer2-Handler-Pool: Thread-607]: session.HiveSessionImpl

created: /tmp/hive/operation_logs/bfe28a51-5804-4cbb-952c-26709aed4652
{code}

But when closing from HS2, we cannot confirm that these directories were deleted. So I change
it so that some messages about these directories deletion may be output as follows.

{code}
2016-02-14T13:57:56,877 INFO  [bfe28a51-5804-4cbb-952c-26709aed4652bfe28a51-5804-4cbb-952c-26709aed4652HiveServer2-Handler-Pool:
