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 > ------------------------------------------------ > > Key: SPARK-2420 > URL: https://issues.apache.org/jira/browse/SPARK-2420 > Project: Spark > Issue Type: Wish > Components: Build > Affects Versions: 1.0.0 > Reporter: Xuefu Zhang > Attachments: spark_1.0.0.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
