Hi team

Quick question.

I am writing a hive generic UDF.

In which, I wanna have this:

HashMap<String, String> vpDefinition =3D new HashMap<String, = String>() ;

vpDefinition.push(=93auction_id=94,=9422=94) ;

The second line always give me FAILED: ClassCastException org.apache.hadoop.io.Text can= not be cast to java.lang.String

When I run the generic udf in hive.

Does anyone know how to deal with this issue ?

I do not understand that, why do I have this cannot cast error. <= /div>

Could anyone explain please ?

Thanks

Dan
