Subject [jira] [Created] (CASSANDRA-4356) Drop column family fail in Cassandra 1.1.1
Date Tue, 19 Jun 2012 22:15:43 GMT
David B created CASSANDRA-4356:
----------------------------------

             Summary: Drop column family fail in Cassandra 1.1.1
                 Key: CASSANDRA-4356
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4356
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.1.1
         Environment: 2-node cluster running on Ubuntu 10.10
            Reporter: David B


2-node v1.1.1 cluster.  Attempts to drop column families appears to succeed, but fails behind
the scenes.  More specifically, the column family is deleted as follows:

cassandra-cli -h HOST_1
> use MyKeyspace
> drop column family MyColumnFamily
79f7ab8c-da08-355c-87a0-8e9630eb4945
Waiting for schema agreement...
... schemas agree across the cluster

Data files in fact have been deleted on HOST_1.  However, the files on HOST_2 still exist
in the /data directory.  Also, the following stack trace appears in /var/log/system.log:

>From this point on, all other Migration commands (e.g. creating new column families) similarly
report no errors, but fail behind the scenes.  Recovering from the erroneous state requires
a cluster restart.
