Subject [jira] [Commented] (HIVE-6316) Document support for new types in HCat
Date Tue, 27 May 2014 10:15:02 GMT


Lefty Leverenz commented on HIVE-6316:

[~ekoifman], here's a first pass ready for review:

* [HCatLoader Data Types |]
* [HCatStorer Data Types |]

More information about onOutOfRangeValue for HCatStorer might be good.  Questions:

* Are Null and Throw the only possible values?
* Where/how does it get specified?
* Should be documented in
* If so, does it belong in the "Data Promotion Behaviour" section?

You also said is out
of date. What needs to be changed there?

> 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
> 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.
