Subbu M Iyer commented on HBASE-4213:
-------------------------------------
Ted,
Yes. DELETE_FAMILY also needs to be added. Will take care of that.
>> You meant recursively deleting the children of node /hbase/schema/<table
>> name>, right ?
Yes.
>> For region server which joins the cluster after the creation of
>> /hbase/schema/<table name>, it should be able to find out that it already
>> reads the most recent HTD. Does it create a child node under
>> /hbase/schema/<table name> ?
The newly joined RS will not create a child under /hbase/schema/<table name> as
it will not be processing the schema change event.
> Support instant schema updates with out master's intervention (i.e with out
> enable/disable and bulk assign/unassign)
