stack commented on HBASE-7390:
------------------------------
bq. What's strange to me is that it seems similar to a RS_ZK_REGION_CLOSED, and
in this case we don't retickle at all: we start the close handler immediately.
Agree we should do one or the other. The tickle does not seem necessary if
when new master joins cluster and it sees a SPLIT, it does the cleanup
immediately -- queues the split handler as is don3 for CLOSED (?).
> Add extra test cases for assignement on the region server and fix the related
> issues
