chunhui shen commented on HBASE-5918:
-------------------------------------

bq.Shouldn't we remove the setting of this flag that happens later in finishInitialization?
In the patch, the setting of this flag is in a if block, so we should keep setting of this flag that happens later in finishInitialization.
