Subject [jira] [Created] (CASSANDRA-13384) Legacy caching options can prevent 3.0 upgrade
Date Tue, 28 Mar 2017 04:20:41 GMT
Jeff Jirsa created CASSANDRA-13384:
--------------------------------------

             Summary: Legacy caching options can prevent 3.0 upgrade
                 Key: CASSANDRA-13384
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13384
             Project: Cassandra
          Issue Type: Bug
          Components: Schema
            Reporter: Jeff Jirsa
            Assignee: Jeff Jirsa
            Priority: Minor
             Fix For: 3.0.x, 3.11.x


In 2.1, we wrote caching options as a JSONified map, but we tolerated raw strings ["ALL",
"KEYS_ONLY", "ROWS_ONLY", and "NONE"|https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/cache/CachingOptions.java#L42].

If a 2.1 node with any of these strings is upgraded to 3.0, the legacy schema migration will
fail.
