Subject [jira] [Updated] (HIVE-14224) LLAP rename query specific log files once a query is complete
Date Sat, 16 Jul 2016 00:01:34 GMT


Siddharth Seth updated HIVE-14224:
    Attachment: HIVE-14224.02.patch

Updated patch.

This has the changes the query-router to log using he queryId and dagId. This is 1) to separate
files for multi-stage queries, and 2) to make it easy to identify the dagId associated with
a queryId (Eventually Hive will hopefully make this available via HS2).

Also updated the HistoryLogger to include a time setup - otherwise log4j2 2.6.x complains
about no date pattern despit using a Time+Size policy.

The bit about not overwriting files for ext queries needs to be fixed. I'll take care of that
in HIVE-14225 or a jira after that which updates the log links on the UI.

[~prasanth_j] - could you please review.

> Once a query is complete, rename the query specific log file so that YARN can aggregate
the logs (once it's configured to do so).
