Andrew Wang commented on HDFS-7411:
-----------------------------------
Nice find Ming, I think you're right. I'm not sure why that unit test still
passes, but the right place to add this check is probably
BlockManager#isNodeHealthyForDecommission. If you want to file a JIRA / patch,
I'd be happy to review.
