Subject: Regarding Hive History File(s).

 

Hello All,

 

What is the purpose of maintaining hive history files which contain session
information like session start, query start, query end, task start, task end
etc.? Are they being used later (say by a tool) for some purpose?

 

I don't see these files being getting deleted from the system ;any
configuration needed to be set  to enable deletion or Is there any design
strategy/decision/rationale for not deleting them at all?

 

Also, in these files I don't see the session end message being logged, is it
reserved for future use?

 

-Mohit
