Andrew Wang commented on HDFS-5359:
-----------------------------------
Cool patch; I had to do some background reading on
ConcurrentModificationException and volatile in HDFS-4522 and friends, but this
patch seems to meet the existing semantics.
+1; I think this is generic enough that it can go in trunk as well as the
branch, so I'm going to mark it PA for jenkins.
