Reuben Kuhnert commented on HIVE-12540:
---------------------------------------

I just tested this, but it worked for me. Is this still an issue?

Declaration:

{code}
public class FunctionTask extends Task<FunctionWork> {
  public static class MyUDF extends UDF {

  }
}
{code}

Test:
{code}
create function udfTest as 'org.apache.hadoop.hive.ql.exec.FunctionTask$MyUDF';
INFO  : Compiling command(queryId=sircodesalot_20160315095656_38c72e48-856e-4ece-94e8-eecc145cc045):
