Xuefu Zhang created HIVE-7371: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
