Subject [jira] [Resolved] (CASSANDRA-3923) Cassandra Nodetool Cleanup causing sstable corruption.
Date Wed, 04 Apr 2012 18:11:23 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-3923?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis resolved CASSANDRA-3923.
---------------------------------------

       Resolution: Cannot Reproduce
    Fix Version/s:     (was: 1.1.0)

As noted on CASSANDRA-3065, I don't think we'll be able to make progress on this without a
pre-corruption snapshot to reproduce the problem with.

(We have also observed bad hardware and buggy virtualization layers to cause corruption; see
CASSANDRA-3878.)

CASSANDRA-4051 is also open to improve streaming reliability which may be relevant.

>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3923
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Tools
>    Affects Versions: 0.8.2
>            Reporter: Samarth Gahire
>              Labels: cleanup, compaction, corruption, nodetool, scrub
>   Original Estimate: 48h
>  Remaining Estimate: 48h
>
> We recently doubled size of our cluster. 
> After that,we ran the cleanup on the old machines in the cluster.
> After that we loaded the data which triggered minor compaction which did not complete
due to corrupt sstables
> This was the case with those machines only on which we ran the cleanup.
> As the cleanup is unavoidable after node addition, what is the way to avoid this problem?
> Is this issue fixed in newer versions of Cassandra(As we are using cassandra-0.8.2)?
> OR 
> Are there any steps / procedure that will avoid need of cleanup after node addition.
> The same issue is reported here: CASSANDRA-3065
