Hello, I have observed very high load on the box, which hosts the META region, so I wanted to try isolating the META region to run on its dedicated box and make sure the RegionServer there does not host any other regions besides META. I stopped all other services (MapReduce and DataNode) on this box in order to reduce the load and I force-migrated all other regions off of that RegionServer with the 'move' command on the hbase shell. After awhile though, the balancer reassigned new regions to this RegionServer again.
I am sure that if I stop the balancer, no other regions will be moved there, but I don't want to do that, since I want the balancer to ensure that the rest of the regions are evenly distrubuted among the cluster. Is there any other way that I can achieve this - making sure that no other regions besides META run on a particular RegionServer? thanks
