> Presently distCp, uses the producer-consumer kind of setup while building the
> listing, the input queue and output queue are both unbounded, thus the
> listStatus grows quite huge.
> Rel Code Part :
> https://github.com/apache/hadoop/blob/trunk/hadoop-tools/hadoop-distcp/src/main/java/org/apache/hadoop/tools/SimpleCopyListing.java#L635
> This goes on bredth-first traversal kind of stuff(uses queue instead of
> earlier stack), so if you have files at lower depth, it will like open up the
> entire tree and the start processing....
