Subject [jira] [Commented] (CASSANDRA-4356) Drop column family fail in Cassandra 1.1.1
Date Wed, 20 Jun 2012 01:18:44 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13397200#comment-13397200
] 

David B commented on CASSANDRA-4356:
------------------------------------

I'm saying that I had to run a different test on the same cluster.  In order to continue with
my work, I had already deleted the data files from the cluster and restarted the cluster,
before I saw your request to get the schema_columnfamily information.

As per my previous comment, I can reproduce at any point now.  Essentially every migration
causes the issue.  If I try to create a column family, I encounter the same.  I need to reboot
the offending node before the column family is available, so that I can stream data to it.
 Then the same issue (i.e. 'invalid UTF Bytes...') occurs if I try to drop the column family.
 Rinse and repeat.

If the above isn't helpful, I can try to completely wipe the 2 nodes (i.e. clearing all system/commit
logs/data files, etc.) and record my steps to reproduce the issue...

> 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 on
HOST_2:

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