Mck SembWever commented on CASSANDRA-2388:
------------------------------------------

{quote}If the cassandra node where the TT resides isn't working, then 
throughput is reduced regardless.
bq. Right: we want it to be blacklisted in that scenario.{quote}
This is making the presumption that the hadoop cluster is only used with CFIF.
The TT could still be useful for other jobs submitted.
Furthermore a blacklisted TT does't automatically come back - it needs to be 
manually restarted. Isn't this creating more headache for operations?
