Subject [jira] Commented: (HBASE-3268) Auto-tune balance frequency based on cluster size
Date Tue, 23 Nov 2010 09:55:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12934795#action_12934795

Andrew Purtell commented on HBASE-3268:
---------------------------------------

+1

Actually I've been considering filing against this as a bug. I have been testing recently
some heavy write scenarios that on current 0.90 pile regions on a single RS and can cause
it to OOME before balancing happens. 

Perhaps at least the default should be 1 minute instead of 5?

> 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"
