Adam Antal commented on HDFS-14159:
-----------------------------------
Hi [~virajith], HDFS-7878 and HDFS-12877 are clean cherry-pick from trunk to
branch-3.0. Also I did some internal testing, and the tests pass. So I thought
I did not need to add them as well, since they just need to be cherry-picked
without any further modification. This issue only concerns HDFS-12882, as it is
not a clean cherry-pick, and has some problems that need to be addressed.
So in case of HDFS-7878 and HDFS-12877 a committer can cherry-pick those to
branch-3.0 from trunk without modification. If you think branch-3.0 patches to
those issues are important, than I can upload those to HDFS-7878 and HDFS-12877.

> 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).
