ryan rawson commented on HBASE-1508:
------------------------------------
HBASE-1558 will cause troubles in this area. It might be the root cause in
fact...
Since the Master relies on the HRS to report it, if it never does we'll never
really close it... but assuming that the region got closed then opened again,
1558 will cause problems with scanners seeing the new region assignment since
the delete will be masking the put.
Code inspecting doesnt seem to suggest there is anything else going on, so can
you try this again with latest trunk?

> {code}
> But that is it, no further processing is done. The regions stays closed, and
> even across a restart it stays closed.
> According to what I got told the region should be automatically reassigned to
> a new server. Please confirm that this is what is expected. If not and the
> above seems right, then please disregard and close issue.
