Sergio Peña commented on HIVE-14029: ------------------------------------ [~Ferd] I will investigate that. However, I see that spark 2.0 is a preview release, and it is not stable yet. Should we want to upgrade to this now? I read on the website that preview releases may contain critical bugs or documentation errors, so I think we should wait until it is officially released as GA. > Update Spark version to 2.0.0 > ----------------------------- > > Key: HIVE-14029 > URL: https://issues.apache.org/jira/browse/HIVE-14029 > Project: Hive > Issue Type: Bug > Reporter: Ferdinand Xu > Assignee: Ferdinand Xu > > There are quite some new optimizations in Spark 2.0.0.
