Colin Patrick McCabe updated HDFS-7278:
---------------------------------------
    Attachment: HDFS-7278.005.patch

[~atm]: Good call.  Doing this right is a bit tricky.  The latest patch gets it right.  I
created a synthetic "block deleted" notification which will get sent on the next IBR.  But
creating this notification doesn't itself trigger an IBR, unlike creating a file.
