-----------------------------------------------------------

In my local I backported HDFS-7878 and HDFS-12877 to branch-3.0 and then I made 
[^HDFS-12882.branch-3.0.000.patch] (which can be applied on the top of the 
branch which has those two commits). I think they're both required for 
HDFS-12882.

> 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).
