>          Components: Shuffle
>    Affects Versions: 1.6.1

> 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.
