                 Key: CASSANDRA-3931
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3931
             Project: Cassandra
          Issue Type: Bug
            Reporter: Peter Schuller
             Fix For: 1.1.0


On a 1.1 cluster we happened to notice that {{nodetool gossipinfo | grep 
SCHEMA}} reported disagreement:

{code}
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:b0d7bab7-c13c-37d9-9adb-8ab8a5b7215d
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:bcdbd318-82df-3518-89e3-6b72227b3f66
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:bcdbd318-82df-3518-89e3-6b72227b3f66
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
  SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f
{code}

However, the result of a thrift {{describe_ring}} on the cluster claims they 
all agree and that {{b0d7bab7-c13c-37d9-9adb-8ab8a5b7215d}} is the schema they 
have.

The schemas seem to "actually" propagate; e.g. dropping a keyspace actually 
drops the keyspace.
