      Description copied from interface: SequenceFileWriter
      Creates a Sequence File by writing the given FlowFile as key/value pairs. The provided FlowFile may be a package of multiple FlowFiles, or just one. The keys for the Sequence File are the flow files' logical names. The values are the flow files' content.
      Specified by:
      writeSequenceFile in interface SequenceFileWriter
      Parameters:
      flowFile - - the FlowFile to write to the Sequence File.
      session - session
      configuration - configuration
      compressionType - compression type
      compressionCodec - compression codec
      Returns:
      the written to SequenceFile flow file
