> BucketingSink creates files with the following pattern
> {noformat}
> partPrefix + "-" + subtaskIndex + "-" + bucketState.partCounter{noformat}
> When using checkpointing you have no control over the extension of the final files generated.
This is incovenient when you are for instance writing files in the avro format because
>  # [Hue|http://gethue.com/] will not be able to render the files as avro See this [file|https://github.com/cloudera/hue/blob/master/apps/filebrowser/src/filebrowser/views.py#L730]
>  # [Spark avro|https://github.com/databricks/spark-avro/] will not be able to read the
files unless you set a special property. See [this ticket|https://github.com/databricks/spark-avro/issues/203]
> It would be good if we had the ability to customize the extension of the files created
