Harsh J resolved HDFS-372.
--------------------------
Resolution: Not A Problem
The invalidation of blocks was deliberately moved onto using the async disk
deletion services to facilitate for large delete operations without blocking
operations.
The remainder of the deletes (except for unfinalizing a block) appear to be
special cases (missing block files while meta continues to exist) under the
FSDataSet implementation and the delBlockFromDisk wouldn't apply to it.
Likely gone stale. Closing out as 'Not a Problem'.
