>            Reporter: Rahul Singhal
>            Assignee: Rahul Singhal

> I upgraded a (NN) HA cluster from 2.2.0 to 2.4.0. After I issued the '-finalizeUpgarde'
command, NN was able to finalize the upgrade but DN couldn't (I waited for the next block
report).
> I think I have found the problem to be due to HDFS-5153. I will attach a proposed fix.
