Subject [jira] [Commented] (HBASE-5959) Add other load balancers
Date Tue, 15 May 2012 22:41:08 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13276298#comment-13276298

Zhihong Yu commented on HBASE-5959:
-----------------------------------

bq. need that info in that format.
Please add such information. Of particular interest is the timing information of the first
several balancing rounds when block location cache is cold.

bq. we can't really estimate the amount of time an iteration will take.
Agreed.

bq. Hence we would have to go back to the timer every iteration through. That would be very
costly.
Since the maximum time allowable in one iteration is passed to balancer, why would using local
timer to gauge elapsed time be expensive ?
