IMPALA-8498: Write column index for floating types when NaN is not present
IMPALA-7307 disabled column index writing for floating point columns
until PARQUET-1222 is resolved. However, the problematic values are
only the NaNs. Therefore we can write column index if NaNs are not
present in data.
Testing:
* Added tests which should fail if a column index is
present while having NaN values in the column.
