Hi, Lars blog (1) mentions that data locality for the region servers is lost when HBase cluster is restarted. It's also mentioned at the end that work is going in HBase to assign regions to RS taking data locality into consideration. The blog entry is 18 months old and so I would like to know if this has been incorporated into the latest HBase release or data locality is lost till a compaction is complete.
