Thiruvel Thirumoolan commented on HIVE-4513:
--------------------------------------------

Thanks [~thejas]. +1. I guess we can close the duplicates HIVE-1708 and 
HIVE-3779.

We back-ported this to Hive10 and it works as expected. [~cdrome] had some 
comments on the patch. These fall in the vicinity but should be addressed as a 
separate JIRA.

1. HiveHistoryViewer.java: Its good as "private void init()"
2. HiveHistoryUtil.java: parseLine() method is not thread-safe. It uses 
parseBuffer which could be modified by multiple threads. Currently only HWA 
uses it.
                
> disable hivehistory logs by default

> 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.
