Stephen Yuan Jiang commented on HBASE-13209:
--------------------------------------------
"Should there be a timeout for the wait ?"
Today, we wait forever on sync operation - this is not changed from PV2
"The TODO's were meant for delete column family, right ?"
TODO for rollback steps
"What if IOE is thrown from mfs.deleteFamilyFromFS() ?"
The procedure would fail.
> Procedure V2 - master Add/Modify/Delete Column Family
