Takeshi Yamamuro commented on SPARK-21533:
------------------------------------------
I feel supporting this function makes little sense because Spark does not use
`MapredContext` inside. But, this is some error-prone, so probably we better
print warning messages or something if the function found in Hive UDFs.
> "configure(...)" method not called when using Hive Generic UDFs
> ---------------------------------------------------------------
>
> Key: SPARK-21533
> URL: https://issues.apache.org/jira/browse/SPARK-21533
> Project: Spark
> Issue Type: Bug
> Components: Java API, SQL
> Affects Versions: 2.1.1
> Reporter: Dean Gurvitz
> Priority: Minor
>
> Using Spark 2.1.1 and Java API, when executing a Hive Generic UDF through the
> Spark SQL API, the configure() method in it is not called prior to the
> initialize/evaluate methods as expected.
> The method configure receives a MapredContext object. It is possible to
> construct a version of such an object adjusted to Spark, and therefore
> configure should be called to enable a smooth execution of all Hive Generic
> UDFs.
