Zhihong Yu commented on HBASE-5165:
-----------------------------------
Patch looks interesting.
Have you verified that the patch fixes the problem ?
{code}
LOG.debug("Waiting on processing of deadserver or initiallizing of
master, deadServersInProgress = "
{code}
The above log should be removed. At least, its frequency should be reduced.
{code}
if (masterServices.getServerManager().areDeadServersInProgress()
|| ((HMaster) server).isInitialized()) {
{code}
I think the above should be:
{code}
if (masterServices.getServerManager().areDeadServersInProgress()
|| !((HMaster) server).isInitialized()) {
{code}
> Concurrent processing of DeleteTableHandler and ServerShutdownHandler may
> cause deleted region to assign again
