Examples of VectorGroupByOperator

org.apache.hadoop.hive.ql.exec.vector.VectorGroupByOperator
Vectorized GROUP BY operator implementation. Consumes the vectorized input and stores the aggregate operators' intermediate states. Emits row mode output.

Examples of org.apache.hadoop.hive.ql.exec.vector.VectorGroupByOperator

    GroupByOperator gbyOp = new GroupByOperator();
    gbyOp.setConf(desc);


    Vectorizer v = new Vectorizer();
    Assert.assertTrue(v.validateOperator(gbyOp));
    VectorGroupByOperator vectorOp = (VectorGroupByOperator) v.vectorizeOperator(gbyOp, vContext);
    Assert.assertEquals(VectorUDAFSumLong.class, vectorOp.getAggregators()[0].getClass());
    VectorUDAFSumLong udaf = (VectorUDAFSumLong) vectorOp.getAggregators()[0];
    Assert.assertEquals(FuncAbsLongToLong.class, udaf.getInputExpression().getClass());
  }
