Subject [jira] [Commented] (HADOOP-12956) Inevitable Log4j2 migration via slf4j

Steve Loughran commented on HADOOP-12956:
-----------------------------------------

Happy for you to do the switch to SLF4J APIs; staying in log4j for our tests, properties &c
something I'll expect to continue though. That shouldn't impact what you do downstream with
the hadoop JARs

no longer officially supported.}}

> A whole framework log4j2 upgrade has to be synchronized, partly for improved performance
brought about by log4j2.
