If I understand the history correctly, round-robin was used in .89, but "retains" is the policy for .90+.
My 2-cents is that if/when region-shuffling is required, I'd rather do that with another utility and keep that out of cluster startup. -----Original Message----- From: saint....@gmail.com [mailto:saint....@gmail.com] On Behalf Of Stack Sent: Wednesday, June 08, 2011 3:56 PM To: user@hbase.apache.org Subject: Re: distribution of regions to servers On Wed, Jun 8, 2011 at 12:50 PM, Ted Yu <yuzhih...@gmail.com> wrote: > I am thinking of creating a new policy for region assignment at > cluster startup which assigns regions from each table in round-robin fashion. > Don't we want to retain assignments on startup since that will ensure greatest locality of data? Round-robin would undo all that (We used to do round-robin but worked hard to make it on restart we kept the pre-restart assignments). St.Ack
