Review Comment:
Using Spark3.2.0 Paruqet 1.12.1 to write a parquet file with Gzip
compression, the write is successful, but the read fails
There is the following exception.

It is found that the `total_uncompressed_size` write is a negative number.
Because `CapacityByteArrayOutputStream#size` may be negative.
