Subject [jira] [Updated] (HIVE-16085) get path-to-alias, path-to-work etc recursively in Hive
Date Thu, 02 Mar 2017 03:03:45 GMT


Sergey Shelukhin updated HIVE-16085:
    Attachment: HIVE-16085.WIP.patch

The patch that makes the methods generic. Need to see where this needs to be applied.

> 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).
