Aaron Fabbri commented on HADOOP-15113:
---------------------------------------
Looks good to me, +1. (Tested in us west 2)
Volatile seems reasonable here. Seems the cheapest we can get is these memory
barriers on the closed flag. Expensive from CPU perspective but I doubt we'll
notice with the other very slow things (s3 accesses) going on here.
