HBase will not balance Regions across RegionServers

avatar
Rising Star

I run CDH 5.2 and have an odd problem. I am running HBase with seven RegionServers and 1200 Regions, but the bulk of the Regions are running on two or three of the RegionServers instead of balancing across all Regions. This leads to a problem where two of the RegionServers run out of memory and fail the Java processes, while the other RegionServers sit idle. Is there a command I can run to balance the Regions across all RegionServers?
