Description

With the latest dev effort, queries that would involve multiple MR jobs should be supported by spark now, except for sorting, multi-insert, union, and join (map join and smb might just work). However, this hasn't be verified and tested. This task is to ensure this is the case. Please create JIRAs for problems found.
