> On our large clusters with, master has failed to startup within specified
> time and aborted itself since it was initializing HDFS block distribution.
> Enable table also takes time for larger tables for the same reason. My
> proposal is to refresh HDFS block distribution at the end of master
> initialization and not at retainAssignment()'s createCluster(). This would
> address HBASE-16570's intention, but avoid the problems we ran into.
