Raghu Angadi updated HADOOP-1035:
---------------------------------
Attachment: HADOOP-1035-2.patch
Attached 2.patch. This includes improvement to clearPath().
clearPath() is called for each block deleted and it does File.compareTo() and
every directory. In this patch, we first guess the likely child from
"subdirXY". The guess would be correct unless layout of the directories changes
in future.
> StackOverflowError in FSDataSet
