Daryn Sharp commented on HDFS-6133:
-----------------------------------
I understand the value of this feature, but I'd like to place a polite -1
pending further discussion. I'm not opposed to the goal of the feature but I'd
like to make sure it's not committed before more evaluation. I'll be posting
joint concerns from an internal brainstorming after this comment.
