Review comment:
@viirya @huaxingao this is because `TestHiveSingleton` uses `local[1]`
while `SharedSparkSession` uses `local[2]` so it will generate 2 Parquet files.
As result, `ParquetScan` will generate 2 input splits which makes the test fail
since the provided value for `expectedPartitionCount` is 1.
