Zoltan Matyus commented on HIVE-24636:
--------------------------------------
Status: I mistakenly created a fix and a PR to _master_. Later I realized that
LogFactory should not be used on _master_ at all (see HIVE-24691). I abandoned
[PR #1910|https://github.com/apache/hive/pull/1910] and started the process in
a new [PR #1917|https://github.com/apache/hive/pull/1917] for _branch-3_. I'm
not sure how to get the change to _branch-3.1_, probably a new cherry-pick and
new PR (after the change is merged to _branch-3_).

> Much the same as [HIVE-7563|https://issues.apache.org/jira/browse/HIVE-7563],
> after ClassLoader is closed in JavaUtils, it should be released by Apache
> Commons LogFactory, or the ClassLoader can't be Garbage Collected, which
> leads to memory leak, exactly our PROD met.
