Alex Araujo commented on PHOENIX-4406:
--------------------------------------

Adding DISABLE/ENABLE syntax ties into HBase semantics nicely. The disadvantage 
is that end users have to roll out a DROP in two steps (DISABLE then a DROP). 
Another option could be to only rollout the DISABLE command and have a cleanup 
job do the rest.
It would still be good to have an option to disallow DROP commands for tables 
that have not been disabled to avoid replication issues.

> Phoenix client applications can drop tables when HBase replication is 
> actively shipping edits.
> Add an option to disable the table in Phoenix's metadata when a DROP TABLE is 
> issued.
> This will allow the HBase table to be dropped by admin actions when it's safe 
> to do so.
