Hi,

I am developing the simple converter from Parquet to Arrow.

https://github.com/masayuki038/parquet-to-arrow

If anyone have not started yet, may I create the JIRA and pull request
about the converter from parquet to arrow?

I would like to develop the converter from Arrow to Parquet and some
features(like Dremio implementation).

thanks.
