Daryn Sharp commented on HDFS-8402:
-----------------------------------

I'm unclear if you are blocking this patch?  I feel it's a bit hardline to deem 
a bug fix for a new feature in 2.7.0 as incompatible.  Would you prefer if I 
ignore the bug and just hack the test to make it pass again?  If no, what are 
my options to move forward?

> HDFS-6663 added the ability to check specific blocks.  The exit code is 
> non-deterministically based on the state (corrupt, healthy, etc) of the last 
> displayed block's last storage location - instead of whether any of the 
> checked blocks' storages are corrupt.  Blocks with decommissioning or 
> decommissioned nodes should not be flagged as an error.
