Xuefu Zhang commented on SPARK-2420:
------------------------------------

[~rxin] As pointed above, Hive and its dependent hadoop components are all on 
guava 11, unless Spark shades or downgrade to a common version, I don't see an 
easy workaround. Same story for servlet-api/jetty.

> Change Spark build to minimize library conflicts

> During the prototyping of HIVE-7292, many library conflicts showed up because 
> Spark build contains versions of libraries that's vastly different from 
> current major Hadoop version. It would be nice if we can choose versions 
> that's in line with Hadoop or shading them in the assembly. Here are the wish 
> list:
> 1. Upgrade protobuf version to 2.5.0 from current 2.4.1
> 2. Shading Spark's jetty and servlet dependency in the assembly.
> 3. guava version difference. Spark is using a higher version. I'm not sure 
> what's the best solution for this.
> The list may grow as HIVE-7292 proceeds.
> For information only, the attached is a patch that we applied on Spark in 
> order to make Spark work with Hive. It gives an idea of the scope of changes.
