stack commented on HBASE-8899:
------------------------------
+1 on commit. You might address below on commit?
Add comment here because it is opaque that FALSE in this map means an ongoing
close.
{code}
- LOG.warn("Attempted open of " + region.getEncodedName()
+ Boolean closing =
regionsInTransitionInRS.get(region.getEncodedNameAsBytes());
{code}
Why not just do if (!closing)? (Let autoboxing provide the rest? Maybe it don't
work)
{code}
+ if (!Boolean.FALSE.equals(closing)) { // Only return
ALREADY_OPENED if not closing
{code}
> Could not open a region on a server where it is being closed

> Looked into the failure of an AM none-flaky test:
> http://54.241.6.143/job/HBase-0.95-Hadoop-2/org.apache.hbase$hbase-server/583/testReport/org.apache.hadoop.hbase.master/TestAssignmentManagerOnCluster/testForceAssignWhileClosing/
> The test failed to open a region on a server where the region was being
> closed. Region server just returned ALREADY_OPENED while the region was
> actually being closed.
