dhruba borthakur commented on HDFS-966:
---------------------------------------
I think we do not introduce any new complexity/race conditions if we prevent
recovering a lease while in safemode. If you folks agree, then this patch
should be ok, isn't it?
Is there a scenario where not recovering a lease during safemode could cause
trouble for the NN?
