Backport to branch-3.2 first considering 3.2.3 is pending release, we need fix 
it ASAP.
Please let me know if we should backport other active branches. Thanks.

[~sodonnell] Agree with you .  One solution is to deep copy the op.

But considering namenode performance, we just deep copy CloseOp block and merge 
the patch to our hdfs cluster(250+ DNs, 270 million block ) . It run well so 
far.

[~kihwal], [~daryn], [~ahussein] any ideas about this corner case which could 
be related to async edit logger bug? It is reported many times by different 
guys.  
[^HDFS-15175-trunk.1.patch] try to fix it by deepcopy way, it could be one 
choice. Do you mind to take reviews?

We encountered this bug in our test environment.

Seems that it can be fixed by a deep copy of the blocks while generate 
FSEditlogOp?
