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.
