Subject [jira] [Created] (CASSANDRA-2571) Invalid super cf incr command puts c* in bad state
Date Tue, 26 Apr 2011 22:55:03 GMT
Invalid super cf incr command puts c* in bad state
--------------------------------------------------

                 Key: CASSANDRA-2571
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2571
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.8 beta 1
            Reporter: Mike Bulman


Run the following via cli:
{noformat}
[default@test] use test;
Authenticated to keyspace: test
[default@test] create column family super with column_type=Super and default_validation_class=CounterColumnType;
d41df8e0-7055-11e0-0000-242d50cf1fbf
Waiting for schema agreement...
... schemas agree across the cluster
[default@test] incr super['0']['0'];
Value incremented.
[default@test] incr super['0']['0']['0'];
null
{noformat}

Obviously the first incr call is invalid, even though it reports otherwise, as well as generates
this exception:
{noformat}
ERROR 17:38:05,871 Fatal exception in thread Thread[COMMIT-LOG-WRITER,5,main]

        ... 1 more
{noformat}

But the second, proper incr call results in a bunch of exceptions and not a real increment.
