Subject [jira] Commented: (HBASE-3268) Auto-tune balance frequency based on cluster size
Date Tue, 23 Nov 2010 17:40:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12934918#action_12934918
] 

Jonathan Gray commented on HBASE-3268:
--------------------------------------

Also, when the master gets a new regionserver on an already running cluster, it should automatically
trigger a balance.

> Right now we only balance the cluster once every 5 minutes by default. This is likely
to confuse new users. When you start a new region server, you expect it to pick up some load
very quickly, but right now you have to wait 5 minutes for it to start doing anything in the
worst case.
> We could/should also add a button/shell command to "trigger balance now"
