Virag Kothari commented on HBASE-11531:
---------------------------------------
bq. Did you do assignment with ZK, or without?
I set hbase.assignment.usezk = true and hbase.assignment.usezk.migrating=true
and had few regions under region-in-transition znode.
Now when I restart master, I see many log statements like
{quote}
Processed region 91cccd287d9335d64a2279f0e8e23c27 in state:
RS_ZK_REGION_OPENED, does nothing since the region is already in transition
{91cccd287d9335d64a2279f0e8e23c27 state=PENDING_OPEN, ts=1405465991480,
server=...
{quote}
After a while, there is a WARN statement
{quote}
Timedout waiting for namespace table to be assigned
{quote}
After this, I cant do most of the master activity as namespace table is not
online according to master. Somehow the master UI also doesn't show up.
