---------------------------------
Summary: Identify a minimum set of JARs needed to ship to Spark
cluster [Spark Branch]
Key: HIVE-7371
URL: https://issues.apache.org/jira/browse/HIVE-7371
Project: Hive
Issue Type: Task
Components: Spark
Reporter: Xuefu Zhang
Currently, Spark client ships all Hive JARs, including those that Hive depends
on, to Spark cluster when a query is executed by Spark. This is not efficient,
causing potential library conflicts. Ideally, only a minimum set of JARs needs
to be shipped. This task is to identify such a set.
We should learn from current MR cluster, for which I assume only hive-exec JAR
is shipped to MR cluster.
We also need to ensure that user-supplied JARs are also shipped to Spark
cluster, in a similar fashion as MR does.
