Parquet schema discovery will fail when the dir is like
{code}
/partitions5k/i=2/_SUCCESS
/partitions5k/i=2/_temporary/
/partitions5k/i=2/part-r-00001.gz.parquet
/partitions5k/i=2/part-r-00002.gz.parquet
/partitions5k/i=2/part-r-00003.gz.parquet
/partitions5k/i=2/part-r-00004.gz.parquet
{code}
{code}
