### What changes were proposed in this pull request? The input query schema of INSERT AS SELECT could be changed after optimization. For example, the following query's output schema is changed by the rule `SimplifyCasts` and `RemoveRedundantAliases`. ```SQL SELECT word, length, cast(first as string) as first FROM view1 ``` This PR is to fix the issue in Spark 2.2. Instead of using the analyzed plan of the input query, this PR use its executed plan to determine the attributes in `FileFormatWriter`. The related issue in the master branch has been fixed by https://github.com/apache/spark/pull/18064. After this PR is merged, I will submit a separate PR to merge the test case to the master. ### How was this patch tested?
