Tom White commented on HADOOP-8545:
-----------------------------------

I wonder whether this would be better hosted outside Hadoop Common, since it's 
an optional feature, and won't get tested against Swift during routine Hadoop 
development. We recommended this course of action for KFS when it became QFS 
recently:

It's a non-trivial amount of code: it adds over 35 Java classes in 9 packages 
to core. Does it add any new dependencies? I tried compiling and it complained 
about not being able to find org.apache.http.HttpHeaders.

It looks like the native implementation supports large files now. If so, then 
the block store implementation is redundant and can be removed.
