Elliott Clark commented on HBASE-11974:
---------------------------------------

bq.And with current master meta is always collocated.

Thats configurable and probably off for 1. 
bq.Table availability method is relatively lightweight. Not measured it, but it should be very fast.
Either way adding another rpc call just for cleanliness of exception name is not a good trade off imo.
