Subject [jira] [Commented] (HBASE-8549) Integrate Favored Nodes into StochasticLoadBalancer
Date Tue, 27 Aug 2013 01:39:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8549?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13750865#comment-13750865

Devaraj Das commented on HBASE-8549:
------------------------------------

[~stack] agree with you generally. There are some (small) number of use cases that might benefit
from purely locality but yeah agree that one balancer is better.

In this patch, the issue is that the FavoredNodes stuff is enabled only when the balancer
configured is FavoredNodeLoadBalancer. We probably can remove that flag or have that flag
be controlled by another configuration...

> Right now we have a FavoredNodeLoadBalancer.  It would be pretty easy to integrate the
favored node list into the strochastic balancer.  Then we would have the best of both worlds.
