Zhihong Yu commented on HBASE-5165:
-----------------------------------
As Stack said:
bq. now when a table is disabled, we now set a flag for the table in zk rather
than do it individually on each region
@Chunhui:
Can you address the above in ServerShutdownHandler ?
> Concurrent processing of DeleteTableHandler and ServerShutdownHandler may
> cause deleted region to assign again
