## What changes were proposed in this pull request? This is a regression in Spark 2.2. In Spark 2.2, we introduced a new way to resolve persisted view: https://issues.apache.org/jira/browse/SPARK-18209 , but this makes the persisted view non case-preserving because we store the schema in hive metastore directly. We should follow data source table and store schema in table properties. ## How was this patch tested? new regression test Author: Wenchen Fan <wenchen@databricks.com> Closes #18360 from cloud-fan/view.
