@kkhatua HDFS allows specifying block size during file creation which
overrides the default file system block size. With this PR, we can have single
HDFS block per Parquet file that can be larger than file system block size ,
without changing file system default block size. I know it is confusing. But,
it is possible to create file with block size that is different from file
system default block size.
