Subject [jira] Commented: (HBASE-3305) Allow round-robin distribution for table created with multiple regions
Date Sun, 05 Dec 2010 04:59:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12966899#action_12966899
] 

Ted Yu commented on HBASE-3305:
-------------------------------

If the total number of regions is small compared to the number of region servers, the benefit
of round-robin is less obvious.
Our use case would do round-robin assignment for every table we create. I have no problem
making this the default.

I plan to move the initialization of mRandomizer out of roundRobinAssignment()  for better
randomness.
