Subject [jira] Commented: (CASSANDRA-1136) NullPointerException in StreamInitiateVerbHandler.java when adding a new node
Date Thu, 27 May 2010 00:01:40 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1136?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12872028#action_12872028
] 

Nahor commented on CASSANDRA-1136:
----------------------------------

I just got the same error again with different steps:
- Created a cluster with 2 nodes
- Added data in the cluster
- Added 2 more nodes (the second after the first one was done)
- Called "nodetool loadbalance" on the very first node of the cluster

Then I got the error one one of the other node (where the node being loadbalanced tried to
send the data)
