[jira] [Created] (PARQUET-241) ParquetInputFormat.getFooters() should return in the same order as what listStatus() returns

Mingyu Kim created PARQUET-241:
----------------------------------

             Summary: ParquetInputFormat.getFooters() should return in the same order as what listStatus() returns
                 Key: PARQUET-241
                 URL: https://issues.apache.org/jira/browse/PARQUET-241
             Project: Parquet
          Issue Type: Bug
    Affects Versions: 1.6.0
            Reporter: Mingyu Kim


Because of how the footer cache is implemented, getFooters() returns the footers in a different order than what listStatus() returns.

When I provided url "hdfs://.../part-00001.parquet,hdfs://.../part-00002.parquet,hdfs://.../part-00003.parquet", ParquetInputFormat.getSplits(), which internally calls getFooters(), returned the splits in a wrong order.
