    https://github.com/apache/nifi/pull/3079
  
    What is the use case for having Parquet files flow through NiFi? I wrote 
ConvertAvroToORC and every time I saw it used, it was immediately followed by 
PutHDFS. So I followed the PutParquet lead and wrote a PutORC for the Hive 3 
NAR. We can't currently do anything with a Parquet file (or ORC for that 
matter) in NiFi, so just curious as to how you envision it being used.
    
    Also I wonder if a ParquetRecordWriter might be a better idea? It would do 
the same thing as a processor but the record processors can read in something 
in any format, not just Avro. This was another impetus for having PutORC 
instead of ConvertAvroToORC.

> *Why*?
> PutParquet support is limited to HDFS. 
> PutParquet bypasses the _flowfile_ implementation and writes the file 
> directly to sink. 
> We need a processor for parquet that works like _ConvertAvroToOrc_.
> *What*?
> _ConvertAvroToParquet_ will convert the incoming avro flowfile to a parquet 
> flowfile. Unlike PutParquet, which writes to the hdfs file system, processor 
> ConvertAvroToParquet would write into the flowfile, which can be pipelined to 
> put into other sinks, like _local_, _S3, Azure data lake_ etc.
