Hi, We have a cluster with unequal machines, some are newer with more disk space, more RAM and stronger CPUs. HDFS amd M/R can be tuned to consume less resources but I was unable to find a way to cause HBase balancer to put less regions on the weaker servers, so now they have the same number of regions as the strong servers, causing them to access HDFS remotely because they don't have enough local disk space to store all their region files.
I noticed that in version 0.97 the stochastic load balancer has some configuration options that might help, but it seems that it doesn't exist in version 0.94.6, which is what I'm using (based on CDH4.3.1). Any suggestions? Thanks. -eran
