Andrew Purtell updated HBASE-9466:
----------------------------------
Description:
Provide a read-only mode for a table. Writes to the table in read-only mode
will be rejected, but read-only mode is different from disable in that:
1. it doesn't offline the regions of the table(hence much more lightweight than
disable)
2. it can serve read requests
Also support a cluster level read only state, a shortcut for setting all tables
served by the cluster into read only mode, with a similar shortcut for resuming
normal operations.
Client write requests to the table(s) set in read only mode should be rejected.
We need an exception for HBCK. When operating in read only mode all writes made
by HBCK should be allowed as an exception.
