[jira] [Created] (CASSANDRA-4471) Unable to drop keyspace
Tuure Laurinolli created CASSANDRA-4471:
-------------------------------------------
Summary: Unable to drop keyspace
Key: CASSANDRA-4471
URL: https://issues.apache.org/jira/browse/CASSANDRA-4471

[jira] [Commented] (CASSANDRA-4471) Unable to drop keyspace
Posted by "Svend Hansen (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-4471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447602#comment-13447602 ]
Svend Hansen commented on CASSANDRA-4471:
-----------------------------------------
We're having the same problem on our build server. Can't drop or alter column families and can't drop keyspace.
We're running cassandra 1.1.3 on Ubuntu 12.04.1 LTS.
We haven't had the problem on any of our test servers which are running 1.1.2 on "Amazon Linux" (based on RedHat).
Not sure if the difference is the Cassandra version (you see it on 1.1.2, right?) or the OS (you all experience this just on Debian?)

[jira] [Comment Edited] (CASSANDRA-4471) Unable to drop keyspace
Posted by "Svend Hansen (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-4471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447602#comment-13447602 ]
Svend Hansen edited comment on CASSANDRA-4471 at 9/5/12 12:53 AM:
------------------------------------------------------------------
We're having the same problem on our build server. Can't drop or alter column families and can't drop keyspace.
We're running cassandra 1.1.3 on Ubuntu 12.04.1 LTS.
We haven't had the problem on any of our test servers which are running 1.1.2 on "Amazon Linux" (based on RedHat).
Not sure if the difference is the Cassandra version (you see it on 1.1.2, right?) or the OS (you all experience this just on Debian?)
Edit: I've installed 1.1.4 on the build server but had to actually delete the data files to get rid of the CFs. I'll see if it happens again with 1.1.4...

[jira] [Commented] (CASSANDRA-4471) Unable to drop keyspace
Posted by "Marco Matarazzo (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-4471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13424962#comment-13424962 ]
Marco Matarazzo commented on CASSANDRA-4471:
--------------------------------------------
Exactly the same problem we got. I had to close the bug as I can't reproduce it (we had to move forward, zap the db and start over with a dump) but if you can nail it down, it would be wonderful.
And I confirm that, when it happens, it's a keyspace-specific problem.

sunjian commented on CASSANDRA-4471:
------------------------------------
yes, i have got this problem as well . it happened to the keyspace which has been running for some days , but not all the keyspaces . when it happened , we can't add/edit/delete both the keyspace and the column family , with any kind of client : cli/cqlsh/thrift/hector . no error returns , but no effects took as well .
