Jimmy Xiang commented on HBASE-11760:
-------------------------------------

I generated the graph with dot. I was thinking to change the labels to numbers, so that I
can add more notes to it. Yes, once it is finalized, we can add it to the refguide.

> When a regionserver reports to master a region transition, we should check the current
region state to be exactly what we expect.
