Examples of POSortedDistinct

org.apache.pig.backend.hadoop.executionengine.physicalLayer.relationalOperators.POSortedDistinct
This operator is a variation of PODistinct, the input to this operator must be sorted already.

Examples of org.apache.pig.backend.hadoop.executionengine.physicalLayer.relationalOperators.POSortedDistinct

            // data is sorted
            for (POToChange distinctToChange : distinctsToChange) {
                numDistinctChanged++;
                PODistinct oldDistinct = (PODistinct) distinctToChange.oper;
                String scope = oldDistinct.getOperatorKey().scope;
                POSortedDistinct newDistinct = new POSortedDistinct(
                        new OperatorKey(scope, NodeIdGenerator.getGenerator()
                                .getNextNodeId(scope)), oldDistinct
                                .getRequestedParallelism(), oldDistinct
                                .getInputs());
                newDistinct.setInputs(oldDistinct.getInputs());
                newDistinct.setResultType(oldDistinct.getResultType());
                distinctToChange.plan.replace(oldDistinct, newDistinct);
                distinctToChange.forEach.getLeaves();
            }
            // Removed POSort, if the successor require a databag, we need to
            // add a PORelationToExprProject
