Prasanth Jayachandran updated HIVE-13027:
-----------------------------------------
Attachment: HIVE-13027.3.patch
[~gopalv] Add appending to llap daemon logs. Also for test failures included
disruptor jars in pom.xml. Should we pack the disruptor jar in hive-exec
instead or can we assume that it will be pulled in transitively and be
available in cluster?

> For LLAP and HS2, some configuration changes can be made to improve logging
> performance
> 1) LOG4j2's async logger claims to have 6-68 times better performance than
> synchronous logger. https://logging.apache.org/log4j/2.x/manual/async.html
> 2) Replace File appenders with RandomAccessFileAppender that claims to be
> 20-200% more performant.
> https://logging.apache.org/log4j/2.x/manual/appenders.html#RandomAccessFileAppender
> Also make async logging configurable.
