> Fix For: 1.2.0
>
>
> Now that we have the record reader/writer services currently in master, it
> would be nice to have reader and writers for Parquet. Since Parquet's API is
> based on the Hadoop Path object, and not InputStreams/OutputStreams, we can't
> really implement direct conversions to and from Parquet in the middle of a
> flow, but we can we can perform the conversion by taking any record format
> and writing to a Path as Parquet, or reading Parquet from a Path and writing
> it out as another record format.
> We should add a PutParquet that uses a record reader and writes records to a
> Path as Parquet, and a FetchParquet that reads Parquet from a path and writes
> out records to a flow file using a record writer.
