-----------------------------------------
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]:

Operation log session directory is 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}
