Examples of org.apache.hadoop.hive.ql.plan.unionDesc

org.apache.hadoop.hive.ql.plan.unionDesc
unionDesc is a empty class currently. However, union has more than one input (as compared with forward), and therefore, we need a separate class.

        new ArrayList<Operator<? extends OperatorDesc>>();
      oplist.add(currOp);
      oplist.add(currOpClone);
      Operator<? extends OperatorDesc> unionOp =
        OperatorFactory.getAndMakeChild(
          new UnionDesc(), new RowSchema(currOp.getSchema().getSignature()), oplist);


      RowResolver unionRR = parseContext.getOpParseCtx().get(currOp).getRowResolver();
      GenMapRedUtils.putOpInsertMap(unionOp, unionRR, parseContext);


      // Introduce a select after the union
