[jira] [Created] (CASSANDRA-6157) Selectively Disable hinted handoff for a data center

sankalp kohli created CASSANDRA-6157:
----------------------------------------

             Summary: Selectively Disable hinted handoff for a data center
                 Key: CASSANDRA-6157
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6157
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: sankalp kohli
            Priority: Minor


Cassandra supports disabling the hints or reducing the window for hints. 
It would be helpful to have a switch which stops hints to a down data center but continue hints to other DCs.
This is helpful during data center fail over as hints will put more unnecessary pressure on the DC taking double traffic. Also since now Cassandra is under reduced reduncany, we don't want to disable hints within the DC.
