Julien Le Dem commented on PARQUET-235:
---------------------------------------
I don't think those were meant to be public.
possibly we want parquet.hadoop.metadata to be blacklisted in the semver plugin.
> Fix compatibility of parquet.metadata with 1.5.0
> ------------------------------------------------
>
> Key: PARQUET-235
> URL: https://issues.apache.org/jira/browse/PARQUET-235
> Project: Parquet
> Issue Type: Bug
> Components: parquet-mr
> Affects Versions: 1.6.0
> Reporter: Ryan Blue
> Priority: Blocker
> Fix For: 1.6.0
>
>
> There are quite a few incompatible changes to {{parquet.metadata}} (see
> below). It seems like it is part of the API because the metadata is exposed.
> Fixing it will be annoying because {{ColumnPath}} was removed entirely.
> If this is public, then we need to fix compatibility.

> Removed Class , access public super synchronized
> Class parquet.hadoop.metadata.ColumnChunkMetaData
