[jira] [Created] (SPARK-15178) Remove LazyFileRegion

Thomas Graves created SPARK-15178:
-------------------------------------

             Summary: Remove LazyFileRegion
                 Key: SPARK-15178
                 URL: https://issues.apache.org/jira/browse/SPARK-15178
             Project: Spark
          Issue Type: Improvement
          Components: Shuffle
    Affects Versions: 1.6.1
            Reporter: Thomas Graves


LazyFileRegion was created so we didn't create a file descriptor before having to send the file. see https://issues.apache.org/jira/browse/SPARK-4307.  The change has been pushed back into Netty to support the same things under the DefaultFileRegion. 

https://github.com/netty/netty/issues/3129
https://github.com/netty/netty/commit/a4450b76d9c786f8b7f76e230938b0200a7188be

It looks like that went into 4.0.25.Final.  I believe at the time we created LazyFileRegion we were on 4.0.23.Final and we are now using 4.0.29.Final so we should be able to use the netty class directly.
