Subject [jira] [Commented] (HBASE-6730) Enable rolling averages in StochasticLoadBalancer
Date Fri, 07 Sep 2012 22:20:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13451063#comment-13451063
] 

Ted Yu commented on HBASE-6730:
-------------------------------

{code}
+  private int numRegionLoadsToRemember = 15;
{code}
May I ask how the default of 15 was obtained ?
{code}
+          master.getConfiguration().getInt("hbase.balancer.statusPeriod", 60000),
{code}
So we keep maximum of 15 minutes worth of status, by default ?

> Now that all of the ServerLoad transitions into pb are done.  the load balancer should
get more updates about the current state of the cluster.  This should be used to allow StochasticLoadBalancer
to get rolling averages.
