[jira] [Resolved] (CASSANDRA-7830) Decommissioning fails on a live node

["Michael Shuler (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-7830?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Shuler resolved CASSANDRA-7830.
---------------------------------------
       Resolution: Not a Problem
    Reproduced In: 2.0.11, 2.0.3  (was: 2.0.3, 2.0.11)

In this case, the error is clear: "data is currently moving to this node; unable to leave the ring"

Without knowing clearly what ring changes were made and the statuses, etc., it's difficult to tell why that occurred. In addition, at this point, the node is gone, so it would be difficult to troubleshoot any longer  :)

> I got the following exception when i was trying to decommission a live node. There is no reference in the manual saying that i need to stop the data coming into this node. Even then, decommissioning is specified for live nodes.
> Can anyone let me know if am doing something wrong or if this is a bug on cassandra part?
> Cassandra Version Used : 2.0.3
