Subject [jira] [Commented] (HIVE-3585) Integrate Trevni as another columnar oriented file format
Date Tue, 08 Jan 2013 04:44:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13546609#comment-13546609

Namit Jain commented on HIVE-3585:
----------------------------------

The main reason that contrib exists is to add new features/projects which are being tested,
may take some time to
mature, and are reasonably stand-alone, so that they dont need many changes in existing code.
New serdes/fileformats/udfs
are good usecases for them.

I dont see why is testing/development in contrib so difficult or different as compared to
development in any other component.
This is the reason why contrib was added, so new stand-alone components can bake. We can definitely
move it from contrib, once
it is mature/safe.

Why is development in contrib such a bad idea ?

SerDe,seems fastutil is a good choice.the shark project use fastutil library as columnar serde
library but it seems too large (almost 15m) for just a few primitive array collection.
