> I am working on enabling favored nodes for HBase (HBASE-15531). Was trying out what happens
if favored nodes is used and HDFS balancer is enabled. Ran the unit test TestBalancer#testBalancerWithPinnedBlocks
from branch-2.8.  There were too many exceptions and error messages with this (output attached)
since pinned blocks can't be moved.
> Is there any way to reduce this logging since block pinning is intentional? On a real
cluster, this could be too much. HDFS-6133 enabled block pinning.
