Description

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

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 (SessionState.java:createPath(693)) - Created local directory: /tmp/hive/bfe28a51-5804-4cbb-952c-26709aed4652
2016-02-14T13:57:52,419 INFO  [HiveServer2-Handler-Pool: Thread-607]: session.SessionState (SessionState.java:createPath(693)) - Created HDFS directory: /tmp/hive/root/bfe28a51-5804-4cbb-952c-26709aed4652/_tmp_space.db
2016-02-14T13:57:52,421 INFO  [HiveServer2-Handler-Pool: Thread-607]: session.HiveSessionImpl (HiveSessionImpl.java:setOperationLogSessionDir(287)) - Operation log session directory is created: /tmp/hive/operation_logs/bfe28a51-5804-4cbb-952c-26709aed4652

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.

2016-02-14T13:57:56,877 INFO  [bfe28a51-5804-4cbb-952c-26709aed4652bfe28a51-5804-4cbb-952c-26709aed4652HiveServer2-Handler-Pool: Thread-607]: session.HiveSessionImpl (HiveSessionImpl.java:cleanupSessionLogDir(690)) - Operation log session directory is deleted: /tmp/hive/operation_logs/bfe28a51-5804-4cbb-952c-26709aed4652
