Wei-Chiu Chuang commented on HDFS-15729:
----------------------------------------
Balancer runs as a separate process, probably not a good idea to add one to NN
web UI.
That said, we recently made balancer a daemon, and which exposes jmx. Maybe we
can add a UI to balancer and let it show progress.
> Show progress of Balancer in Namenode UI

> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: balancer & mover
> Affects Versions: 3.1.4
> Reporter: Srinivasu Majeti

> It would be nice to have a tracking of Balancer process in the Namenode UI to
> show if something is running and what is the progress to show current status
> . This would be similar to Namenode startup progress.
