spark using two different versions of netty?
Hi,
quick question, why is Spark using two different versions of netty?:
- io.netty:netty-all:4.0.29.Final:jar
- io.netty:netty:3.8.0.Final:jar
?

Yeah, I should be more precise. Those are two direct dependencies.

Usually this sort of thing happens because the two versions are in
different namespaces in different major versions and both are needed. That
is true of Netty: http://netty.io/wiki/new-and-noteworthy-in-4.0.html
However, I see that Spark declares a direct dependency on both, when it
does not use 3.x directly (and should not). The exception is in the Flume
module, but that could be handled more narrowly. I will look into fixing
this if applicable.
