> HadoopOutFormat OutputCommitter is default to FileOutputCommiter
> ----------------------------------------------------------------

> Key: FLINK-2394
> URL: https://issues.apache.org/jira/browse/FLINK-2394
> Project: Flink
> Issue Type: Bug
> Components: Hadoop Compatibility
> Affects Versions: 0.9.0
> Reporter: Stefano Bortoli
> Assignee: Fabian Hueske
> Fix For: 0.10, 0.9.1
>
>
> MongoOutputFormat does not write back in collection because the
> HadoopOutputFormat wrapper does not allow to set the MongoOutputCommiter and
> is set as default to FileOutputCommitter. Therefore, on close and
> globalFinalize execution the commit does not happen and mongo collection
> stays untouched.
> A simple solution would be to:
> 1 - create a constructor of HadoopOutputFormatBase and HadoopOutputFormat
> that gets the OutputCommitter as a parameter
> 2 - change the outputCommitter field of HadoopOutputFormatBase to be a
> generic OutputCommitter
> 3 - remove the default assignment in the open() and finalizeGlobal to the
> outputCommitter to FileOutputCommitter(), or keep it as a default in case of
> no specific assignment.
