> The Balancer makes a check to see if a block's location is a known data node. But the variable it uses to check is wrong. This issue was fixed in HDFS-6364.
> There was no way to easily unit test it at that time. Since HDFS-6441 enables one to simulate this case, it was decided to add the unit test once HDFS-6441 is resolved.
