    There was a bug (PARQUET-246) in which DeltaByteArrayWriter's reset() method did not clear the previous value state that it tracks internally.

    There was a bug (PARQUET-246) in which DeltaByteArrayWriter's reset() method did not clear the previous value state that it tracks internally. This resulted in the first value of all pages (except for the first page) to be a delta from the last value of the previous page. In order to read corrupted files written with this bug, when reading a new page we need to recover the previous page's last value to use it (if needed) to read the first value.
