-------------------------------------

             Summary: Remove LocalCollectionOutputFormat from code base
                 Key: FLINK-21993
                 URL: https://issues.apache.org/jira/browse/FLINK-21993
             Project: Flink
          Issue Type: Improvement
          Components: API / DataSet, Library / Graph Processing (Gelly), Table SQL / Planner
            Reporter: Till Rohrmann


The {{LocalCollectionOutputFormat}} is not safe wrt to failovers. The problem is that it records also partial results from previous attempts. I would suggest to remove this class. See FLINK-21609 for an example problem.
