---------------------------------------

             Summary: get path-to-alias, path-to-work etc recursively in Hive
                 Key: HIVE-16085
                 URL: https://issues.apache.org/jira/browse/HIVE-16085
             Project: Hive
          Issue Type: Task
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


Sometimes, we don't get correct alias/part desc/etc. from paths - e.g. in HIVE-15870 (for MM tables).
We have methods in utils for partdescs to work around that, but they are not applied consistently. I suspect people add calls to this method after they discover some particular path is broken; perhaps we should find such places proactively for path-to-part, path-to-work, and path-to-alias maps.
This can happen much more with MM tables, but can also happen for any recursive-path cases (incl. just a regular recursive path read enabled via an MR config).
