[jira] [Commented] (CASSANDRA-4445) balance utility for vnodes

    [ https://issues.apache.org/jira/browse/CASSANDRA-4445?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13550367#comment-13550367 ] 

Brandon Williams commented on CASSANDRA-4445:
---------------------------------------------

I think that given the difficulty of doing this programmatically, even if we knew the load per token (which we don't), the best thing to do here is expose relocate to the user and let them manage it themselves, if need be.

> We need a 'balance' utility similar to move without a token, in the cases where entropy is not your friend and gives you an unbalanced cluster (I've seen up to a 7% discrepancy myself)
