> Similar to the existing LocalCollectionOutputFormat or Spark's collect() method, it would be nice to have a CollectionOutputFormat that also works when running jobs on a cluster. This output format gathers all results of a sink from all TaskManagers in the JVM that submitted the job plan and provides these as a collection, similar to accumulators. After all, this can help to avoid the tedious task of going to HDFS and read and parse the single result files.
> PS. We have already created such an output format and can contribute it.
