Subject [jira] [Commented] (CASSANDRA-2773) "Index manager cannot support deleting and inserting into a row in the same mutation"
Date Wed, 29 Jun 2011 15:35:28 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2773?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13057298#comment-13057298

Jim Ancona commented on CASSANDRA-2773:
---------------------------------------

We have deployed and tested 0.7.6 plus this patch to the affected cluster. The cluster restarted
successfully and the tests that caused the original failure ran successfully. In addition,
functional tests of our applications show no regressions. I also reviewed the Cassandra system
logs after the testing and saw no errors or obvious problems.

> I use hector 0.8.0-1 and cassandra 0.8.
> 1. create mutator by using hector api, 
> 2. Insert a few columns into the mutator for key "key1", cf "standard". 
> 3. add a deletion to the mutator to delete the record of "key1", cf "standard".

> 5. execute the mutator.

I tried to restart the cassandra I saw unsupportedexception : "Index manager cannot support
deleting and inserting into a row in the same mutation". and the cassandra is dead forever,
unless I delete the commitlog. 
> I would expect to get an exception when I execute the mutator, not after I restart the
cassandra.
