      Description

      `convertMetastoreOrc/Parquet` ignores table properties.

      This happens for a table created by `STORED AS ORC/PARQUET`.

      Currently, `convertMetastoreParquet` is `true` by default. So, it's a well-known user-facing issue. For `convertMetastoreOrc`, it has been `false` and SPARK-22279 tried to turn on that for Feature Parity with Parquet.

      However, it's indeed a regression for the existing Hive ORC table users. So, it'll be reverted for Apache Spark 2.3 via https://github.com/apache/spark/pull/20536 .
