Subject [jira] [Updated] (HBASE-5959) Add other load balancers
Date Fri, 11 May 2012 21:57:49 GMT

     [ https://issues.apache.org/jira/browse/HBASE-5959?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Elliott Clark updated HBASE-5959:

    Attachment: HBASE-5959-2.patch

* More JavaDoc's to explain things better
* Scale all cost functions between 0 and 1.  This should allow weighting to be more transparent
and cleans up some of the math.
* Added a cost function that takes data locality into consideration.
* Added a Class to look up data locality.  Removing that from the base class.  I had to add
a cache or the load balance is painfully slow.
* Cleaned up a lot of code.
* Added lots more tests for StochasticLoadBalancer.
