Subject [jira] [Created] (CASSANDRA-4384) HintedHandoff can begin before SS knows the hostID
Date Wed, 27 Jun 2012 19:01:44 GMT
Brandon Williams created CASSANDRA-4384:
-------------------------------------------

             Summary: HintedHandoff can begin before SS knows the hostID
                 Key: CASSANDRA-4384
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4384
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.2
            Reporter: Brandon Williams
             Fix For: 1.2


Since HH fires from the FD, SS won't quite have the hostId yet:

Simple solution seems to be getting the hostId from gossip instead.
