Geoffrey Yu updated CASSANDRA-12311:
------------------------------------
Description: Right now if a data node fails to perform a read because it
ran into a {{TombstoneOverwhelmingException}}, it only responds back to the
coordinator node with a generic failure. Under this scheme, the coordinator
won't be able to know exactly why the request failed and subsequently the
client only gets a generic {{ReadFailureException}}. It would be useful to
inform the client that their read failed because we read too many tombstones.
We should have the data nodes reply with a failure type so the coordinator can
pass this information to the client. (was: Right now if a data node fails to
