Current Behavior

When try to write multiple data frame like:

    val offsetChunks = edgeDfAndOffsetDf._2.par
    offsetChunks.foreach { case (i, offsetChunk) =>
      FileSystem.writeDataFrame(
        offsetChunk,
        FileType.FileTypeToString(fileType),
        outputPrefix,
        Some(i),
        None
      )
      offsetChunk.unpersist()
    }

got error

Expected Behavior
