Subject [jira] [Commented] (HIVE-2482) Convenience UDFs for binary data type
Date Thu, 01 Aug 2013 17:21:49 GMT

Edward Capriolo commented on HIVE-2482:

I usually write end to end tests for new features (mostly for regression testing but also
to demonstrate what functionality is getting introduced). For bug fixes I write junit tests
to test the part which I am fixing.
 Obviously there are lot more bug fixes than features, so in most circumstances junit tests
are encouraged, though in this particular instance there are new udfs (thus new features)
so here end to end tests does make sense.

Well said. Hive is releasable trunk, so every commit for a new feature has to be usable. q
tests show the usable. 

Moreover the q tests serve as the ONLY true documentation we have, since most things never
hit the wiki.

> HIVE-2380 introduced binary data type in Hive. It will be good to have following udfs
to make it more useful:
> * UDF's to convert to/from hex string
> * UDF's to convert to/from string using a specific encoding
> * UDF's to convert to/from base64 string
> * UDF's to convert to/from non-string types using a particular serde
