[jira] [Commented] (HIVE-11304) Migrate to Log4j2 from Log4j 1.x

["Xuefu Zhang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-11304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15005687#comment-15005687 ] 

Xuefu Zhang commented on HIVE-11304:
------------------------------------

[~prasanth_j], it looks like that this has broken Spark test in such a way that no hive.log is generated. To reproduce, run the following in itests/:
{code}
mvn test -Dtest=TestSparkCliDriver -Dqfile=orc_merge1.q -Phadoop-2
{code}
Reverting the patch here fixes the problem. The following is the location of the expected hive.log:
{code}
./itests/qtest-spark/target/tmp/log/hive.log
{code}
Please take a look.

> 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.
