> Key: CASSANDRA-3037
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3037
> Project: Cassandra
> Issue Type: Bug
> Components: Hadoop
> Affects Versions: 0.8.4
> Environment: Ubuntu 10.04 LTS
> Hadoop from Cloudera 0.20.203
> Latest java
> Reporter: Anton Vedeshin
> Priority: Blocker
>
> After upgrade of cassandra from 0.8.2 to 0.8.4, got this error, before
> upgrade everything was working fine
> I have restarted cassandra, removed data, etc. nothing helps
> I have 6 identical machines in the cloud, before it was working fine. If I
> make netstat then it shows port 9160 listening nodetool ... ring - responces
> with 6 machines UP.
> Finally I have truncated all 6 servers and reinstalled hadoop + cassandra
> 0.8.4 from scratch.
> compiled and tried to execute word_cound
> receive the same error as after upgrade
