Lefty Leverenz commented on HIVE-6316:
--------------------------------------
[~ekoifman], here's a first pass ready for review:
* [HCatLoader Data Types |
https://cwiki.apache.org/confluence/display/Hive/HCatalog+LoadStore#HCatalogLoadStore-HCatLoaderDataTypes]
* [HCatStorer Data Types |
https://cwiki.apache.org/confluence/display/Hive/HCatalog+LoadStore#HCatalogLoadStore-HCatStorerDataTypes]
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 hcat.pig.store.onoutofrangevalue be documented in
https://cwiki.apache.org/confluence/display/Hive/HCatalog+Config+Properties?
* If so, does it belong in the "Data Promotion Behaviour" section?
You also said
https://cwiki.apache.org/confluence/display/Hive/HCatalog+InputOutput is out of
date. What needs to be changed there?
> 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.
