Subinterfaces of GenericUDAFResolver in org.apache.hadoop.hive.ql.udf.generic
 interface GenericUDAFResolver2
          This interface extends the GenericUDAFResolver interface and provides more flexibility in terms of discovering the parameter types supplied to the UDAF.
 

Classes in org.apache.hadoop.hive.ql.udf.generic that implement GenericUDAFResolver
