Tom White commented on HDFS-1170:
---------------------------------
+1
I think this can be committed (to 0.21 and trunk). I ran
TestLargeDirectoryDelete 10 times and got 8 NullPointerExceptions. With this
patch I got no failures and no NPEs in 10 runs, so it fixes HDFS-1170 for me
(this is on a Mac).
