Prasanth Jayachandran commented on HIVE-11304:
----------------------------------------------

I just tried the steps you have mentioned in master branch and I can see the logs generated
at ./qtest-spark/target/tmp/log/hive.log. Can you post the output from qtest-spark/target/surefire-reports/org.apache.hadoop.hive.cli.TestSparkCliDriver-output.txt?

> Log4J2 has some great benefits and can benefit hive significantly. Some notable features
include
> 1) Performance (parametrized logging, performance when logging is disabled etc.) More
details can be found here https://logging.apache.org/log4j/2.x/performance.html
> 2) RoutingAppender - Route logs to different log files based on MDC context (useful for
HS2, LLAP etc.)
> 3) Asynchronous logging
> This is an umbrella jira to track changes related to Log4j2 migration.
