Lefty Leverenz commented on HIVE-6316:
--------------------------------------
Should I just add new data types to the HCatRecord table, along with their Java
classes, range of values, and Hive release information? Decimal, tinyint, and
smallint are already on the list, so I would add:
* date
* timestamp
* char
* varchar
If so, what are their Java classes? (Hm, range of values doesn't seem to apply
to these types.)
> Document support for new types in HCat

> Key: HIVE-6316
> URL: https://issues.apache.org/jira/browse/HIVE-6316
> Project: Hive
> Issue Type: Sub-task
> Components: Documentation, HCatalog
> Affects Versions: 0.13.0
> Reporter: Eugene Koifman
> Assignee: Lefty Leverenz
>
> HIVE-5814 added support for new types in HCat. The PDF file in that bug
> explains exactly how these map to Pig types. This should be added to the
> Wiki somewhere (probably here
> https://cwiki.apache.org/confluence/display/Hive/HCatalog+LoadStore).
> In particular it should be highlighted that copying data from Hive TIMESTAMP
> to Pig DATETIME, any 'nanos' in the timestamp will be lost. Also, HCatStorer
> now takes new parameter which is described in the PDF doc.
