Thiruvel Thirumoolan updated HDFS-11401:
----------------------------------------
Description:
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.
