Adam Antal commented on HDFS-14159:
-----------------------------------
Thanks for the clarification [~jojochuang], I see it now.
So to sum it up, since this patch and its prerequisites are massive commits and
they probably do not contribute to the stability of the maintenance release,
you suggest that it should NOT be backported.

> Key: HDFS-14159
> URL: https://issues.apache.org/jira/browse/HDFS-14159
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs
> Affects Versions: 3.0.3
> Reporter: Adam Antal

> This task aims to backport HDFS-12882 and some connecting commits to
> branch-3.0 without introducing API incompatibilities.
> In order to be able to cleanly backport, first HDFS-7878, then HDFS-12877
> should be backported to that branch as well (both can be executed cleanly,
> and with build success).
> Also, this patch would also introduce API backward incompatibilities in
> hadoop-hdfs-client, and we should modify it to a compat change (similar as in
> HDFS-13830 fought with this problem).
