Brock Noland updated HIVE-9127:
-------------------------------
Description:
In HIVE-7431 we disabled caching of Map/Reduce works because some tasks would
fail. However, we should be able to cache these objects in RSC for split
generation. See:
https://issues.apache.org/jira/browse/HIVE-9124?focusedCommentId=14248622&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14248622
