Danny Becker commented on HDFS-8591:
------------------------------------
There is an issue with the logic here which can cause the decommissioner to get
stuck in a nearly infinite loop. The decommissioner checks a datanode which is
in_maintenance and no blocks are checked. The decommissioner will continue to
loop through this until the datanode is no longer in_maintenance or it reaches
Integer.MAX_VALUE.
