Julien Le Dem resolved PARQUET-1259.
------------------------------------
Resolution: Workaround
supporting more than one version adds complexity.
It sounds like people can use protobuf 2 syntax with protobuf 3 library
I would recommend that instead.
I'll close this for now.
Please re-open if this is not satisfying.
> Parquet-protobuf support both protobuf 2 and protobuf 3
> -------------------------------------------------------
>
> Key: PARQUET-1259
> URL: https://issues.apache.org/jira/browse/PARQUET-1259
> Project: Parquet
> Issue Type: New Feature
> Affects Versions: 1.10.0, 1.9.1
> Reporter: Qinghui Xu
> Priority: Major
>
> With the merge of pull request:
> [https://github.com/apache/parquet-mr/pull/407,] now it is protobuf 3 used in
> parquet-protobuf, and this implies that it cannot work in an environment
> where people are using protobuf 2 in their own dependencies because there is
> some new API / breaking change in protobuf 3. People have to face a
> dependency version conflict with next parquet-protobuf release (e.g. 1.9.1 or
> 1.10.0).
> What if we support both protobuf 2 and protobuf 3 by providing
> parquet-protobuf and parquet-protobuf2?
