[jira] [Created] (CASSANDRA-6732) Cross DC writes not compatible 1.2->1.1 during rolling upgrade

Jeremiah Jordan created CASSANDRA-6732:
------------------------------------------

             Summary: Cross DC writes not compatible 1.2->1.1 during rolling upgrade
                 Key: CASSANDRA-6732
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6732
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Jeremiah Jordan


During a rolling upgrade from 1.1.12 to 1.2.15 one DC at a time only 1/3 of the writes to the first DC to be upgraded actually make it to the other DC, and LOTS of hints attempt to get made.

Looks like the header for forwarded writes changed from 1.1->1.2 so the 1.1 nodes can't read it.
