Gopal V commented on HIVE-13027:
--------------------------------
[~prasanth_j]: yes, some jars to be bundled - HIVE-13015 (see .3 patch).
Confirmed a run of TPC-DS Q55 using 1 node with INFO logging ran in ~0.6
seconds, but my INFO logs are going to console.
Trying to figure out how the llap log4j is loaded up by the Configurator (is it
still reading hive-exec-log4j2.properties?).

> 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
> We should use that for LLAP.
