Yep. Seems stale. You can try to comment on it to revive.

Hmm... So that's an interesting bug then. Might filing a jira? -- Lars ----- Original Message ----- From: Vladimir Rodionov <vrodio...@carrieriq.com> To: "dev@hbase.apache.org" <dev@hbase.apache.org>; lars hofhansl <la...@apache.org> Cc: Sent: Monday, July 22, 2013 3:30 PM Subject: RE: Smarter Region assignment policy? OK, you right and I was not. If I do not disable/enables tables after cluster restart all regions seem get assigned correctly. I think its disabling/enabling tables shuffles regions in a bad way.

This is the one: https://issues.apache.org/jira/browse/HBASE-4402 I assume you let the master wait sufficiently to give all RegionServer a chance to sign in? -- Lars ________________________________ From: lars hofhansl <la...@apache.org> To: "dev@hbase.apache.org" <dev@hbase.apache.org> Sent: Monday, July 22, 2013 11:55 AM Subject: Re: Smarter Region assignment policy? I faintly remember there was a jira that attempted to assign the regions to the same region servers after a restart based on existing .META. information (if possible). Will try to find that and see why it is not working as expected. -- Lars ________________________________ From: Vladimir Rodionov <vrodio...@carrieriq.com> To: "dev@hbase.apache.org" <dev@hbase.apache.org> Sent: Monday, July 22, 2013 11:43 AM Subject: RE: Smarter Region assignment policy? Yes, its related but not what I am looking for. Locality index is approaching to 100% after major compaction of all tables. Its often > 90% during regular operation of a cluster, but is far below 50% when cluster restarts. Can assignment manager take into account previous region assignments on node/cluster start up? That is what I am looking for. How hard is to implement this feature?
