             Summary: Merging parquet files created in 1.11.1 not possible using 1.12.0 
                 Key: PARQUET-2027
                 URL: https://issues.apache.org/jira/browse/PARQUET-2027
             Project: Parquet
          Issue Type: Bug
          Components: parquet-mr
    Affects Versions: 1.12.0
            Reporter: Matthew M


I have parquet files created using 1.11.1. In the process I join two files (with the same schema) into a one output file. I create Hadoop writer:
{code:scala}
val hadoopWriter = new ParquetFileWriter(
      HadoopOutputFile.fromPath(
        new Path(outputPath.toString),
        new Configuration()
      ), outputSchema, Mode.OVERWRITE,
      8 * 1024 * 1024,
      2097152,
      DEFAULT_COLUMN_INDEX_TRUNCATE_LENGTH,
      DEFAULT_STATISTICS_TRUNCATE_LENGTH,
      DEFAULT_PAGE_WRITE_CHECKSUM_ENABLED
    )
    hadoopWriter.start()
{code}
and try to append one file into another:
{code:scala}
hadoopWriter.appendFile(HadoopInputFile.fromPath(new Path(file), new Configuration()))
{code}
Everything works on 1.11.1. But when I've switched to 1.12.0 it fails with that error:
{code:scala}
