Github user gatorsmile commented on the issue: https://github.com/apache/spark/pull/16281 The problem is the Parquet community will not create a branch 1.8.2+ for us. Upgrading to newer versions 1.9 or 2.0 are always risky. Based on the history, we hit the bugs and performance degradation, when we try to upgrade the Parquet versions. We need more time and efforts to decide whether we need to upgrade to the newer Parquet version.
