Subject [jira] Commented: (HBASE-2473) Add to admin create table start and end key params and desired number of regions
Date Sun, 25 Jul 2010 15:06:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12892104#action_12892104

Ted Yu commented on HBASE-2473:
-------------------------------

I think ServerManager.getAverageLoad() should be revised to handle the intricacies introduced
by this JIRA.
Since the distribution of keys among (byte [][]) splitKeys may not be even, it is less accurate
to compute average load using the current formula. Considering that some of the empty regions
may stay empty.
The related test case is TestRegionRebalancing.
