Viraj Jasani commented on HBASE-23909:
--------------------------------------
With master branch, I am not able to repro this. Some regions are stuck in
trasition, so the output comes like this:

However, I see that we have already backported this to branch-1 last year:
[https://github.com/apache/hbase/commit/ac807d7fe53e000aa3bc7be93df9b16028efddce]
Let me try to reproduce today with branch-1.

> Here is some help for this command:

> The command displays server name, region name, start key, end key,
