Andrew Purtell commented on HBASE-11747:
----------------------------------------
We can add *new* APIs. I wonder if it would be workable to introduce a
streaming status API where the client uses a cursor to iterate over the
master's picture of the cluster. Might be tricky wherever regions have migrated
or servers have come and gone. The master would have to provide either a
consistent snapshot of state or track changes since the client opened the
curser and mix in change deltas with iteration results.
