> HiveHistory log files (hive_job_log_hive_*.txt files) store information about hive query
such as query string, plan , counters and MR job progress information.
> There is no mechanism to delete these files and as a result they get accumulated over
time, using up lot of disk space. 
> I don't think this is used by most people, so I think it would better to turn this off
by default. Jobtracker logs already capture most of this information, though it is not as
structured as history logs.
> HIVE-4500 is introducing a new config parameter to turn this off, we should use that
to turn this off by default.
