nkeywal commented on HBASE-7390:
--------------------------------
bq. Why does master not see SPLITTING? Because it does not have a watcher? It
cannot create a znode when there is a SPLITTING znode in place though. That is
what we want, right? Ditto for the OPENING? Does the master not have a watcher
on the OPENING znode?
I need to explore the splitting case, but there are no real reason imho (at
least not a ZK reason).
bq. testMultipleOpen
I'm on this one (see comment above), it's not easy. The fix is trivial. What it
is revealing is not.
> Add extra test cases for assignement on the region server
