Make sure you have checked _all_ steps below. The `CODEC_BY_NAME` is static and may be used across different configurations. If a codec is initialized it will be re-used no matter what the configuration is. This is a problem when there are different compression levels used. https://github.com/apache/parquet-mr/blob/515734c373f69b5250e8b63eb3d1c973da893b63/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/CodecFactory.java#L45-L46 Therefore we need to cache per compression level as well. ### Jira - [ ] My PR addresses the following [Parquet Jira](https://issues.apache.org/jira/browse/PARQUET/) issues and references them in the PR title.
