> Reusing the Schema object from a Parquet file written with Spark with Pandas fails due to Schema mismatch.
> The culprit is in the metadata part of the schema which each component fills according to it's implementation. More details can be found here: [https://github.com/apache/arrow/issues/2805]
> The documentation should point that out.
