Github user mxm commented on the pull request: https://github.com/apache/flink/pull/966#issuecomment-126705428 Thanks for the pull request! You did not convert all InputFormats and OutputFormats. There are a few more, e.g. HadoopInputFormatBase or JDBCInputFormat. Other than that, your pull request looks good. I think it is fine to keep the notion of normal and rich, just like we do for the operator user functions. That also means that we do not break the existing interfaces.
