Subject [jira] [Commented] (HBASE-13895) DATALOSS: Double-assignment ITBLL'ing

Enis Soztutar commented on HBASE-13895:
---------------------------------------

bq. What you thinking on this one Enis Soztutar? Thanks.
Let's get this in. Let me update the patch because even in regular RS shutdown, it can happen
that the master tries to close the region, does an RPC, and the RPC throws RegionServerStoppedException.
AM continues to assign the region although there is no guarantee that the RS has actually
closed the region (thus everything is flushed). We start throwing RSSE while region server
is closing. There is no ordering guarantee for the regions to be actually closed.

> I have dataloss running ITBLL at 3B (testing HBASE-13877). Most obvious culprit is the
double-assignment that I can see.
