### What changes were proposed in this pull request? This PR adds a test to verify that the compression codec specified in `spark.sql.parquet.compression.codec` is correctly applied to Hive tables and directories during table creation and data insertion. ### Why are the changes needed? We add compression codec through `setupHadoopConfForCompression` and keep compress codec in hadoopConf: https://github.com/apache/spark/blob/3e0808c33f185c13808ce2d547ce9ba0057d31a6/sql/hive/src/main/scala/org/apache/spark/sql/hive/execution/V1WritesHiveUtils.scala#L114-L141 However, we might accidentally use `sparkSession.sessionState.newHadoopConf()` instead of the old hadoopConf. This can cause the compression codec to be lost. So, we add a test to make sure this does not happen. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Manual test. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service.
