Subject [GitHub] flink pull request: [FLINK-3560] [examples] Remove unchecked outpu...

Github user vasia commented on the pull request:

    If we remove the default usage printing, I think it would be nice to make sure that all
examples implement `ProgramDescription`. This way, we can get the usage information if we
want to. Otherwise, we would get one message per default parameter. e.g. in the Kmeans example,
we would get:
    Executing K-Means example with default point data set.
    Use --points to specify file input.
    Executing K-Means example with default centroid data set.
    Use --centroids to specify file input.
    Printing result to stdout. Use --output to specify output path.
    instead of
    `Usage: KMeans --points <path> --centroids <path> --output <path> --iterations
