Subject [jira] [Commented] (HIVE-2482) Convenience UDFs for binary data type

Is it reasonable to say that we strongly encourage unit testing but we'd like to see at least
one end to end test?

^ that has always been the case.
I am ok with moving to a simpler/faster/east to test style. But asserting on evaluate() really
does not cover everything  (because of the state). Neither does select udf(x) from src limit
1 (bugs from multiple rows). I think we need to be simulating from the standpoint of an operator
interacting with the UDF normally. It would not be full end-to-end but more then just cherry
picking execution points and validating results.

> 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
