Rui Li commented on HIVE-14029:
-------------------------------
[~Ferd], you mean unit test will fail right? I don't see failed spark qtest in
last QA report. For qtest/runtime, we use spark-submit to submit the app, so
spark should add all its dependencies to classpath. One problem I can think of
is if we don't exclude the glassfish jersey, will hive pull two versions of
jersey into its classpath, i.e. the lib dir? If so, that can cause problem for
hive's functionalities that depend on jersey.
> Update Spark version to 2.0.0

> There are quite some new optimizations in Spark 2.0.0. We need to bump up
> Spark to 2.0.0 to benefit those performance improvements.
> To update Spark version to 2.0.0, the following changes are required:
> * Spark API updates:
> ** SparkShuffler#call return Iterator instead of Iterable
> ** SparkListener -> JavaSparkListener
> ** InputMetrics constructor doesn’t accept readMethod
> ** Method remoteBlocksFetched and localBlocksFetched in ShuffleReadMetrics
> return long type instead of integer
> * Dependency upgrade:
> ** Jackson: 2.4.2 -> 2.6.5
> ** Netty version: 4.0.23.Final -> 4.0.29.Final
> ** Scala binary version: 2.10 -> 2.11
> ** Scala version: 2.10.4 -> 2.11.8
