David Mollitor commented on HIVE-22409:
---------------------------------------
I think logging can certainly be better. I've worked on some areas of this
already. However, I wouldn't be a favor of this. There would have to be some
facilities for managing these logs for creation, tracking in the code which log
file a message should go to and for making sure they get cleared up. Seems
like a lot of overhead to do that well. I think it's best to keep it simple
and make sure that more logging includes the sessionID so that a simple 'grep'
will suffice.

> Logging: Implement QueryID Based Hive Logging
> ---------------------------------------------
>
> Key: HIVE-22409
> URL: https://issues.apache.org/jira/browse/HIVE-22409
> Project: Hive
> Issue Type: Improvement
> Reporter: Syed Shameerur Rahman
> Assignee: Syed Shameerur Rahman
> Priority: Minor
>
> Currently all the hive logs are logged in
> ${sys:hive.log.dir}/${sys:hive.log.file} which is basically a single log
> file. Over the time it becomes tedious to search for logs since multiple hive
> query logs are logged into single log file.
> Hence we propose a queryID based hive logging where logs of different queries
> are logged into a separate log file based on their queryID.
