gengliangwang opened a new pull request #23491: [SPARK-26571][SQL] Update Hive Serde mapping with canonical name of Parquet and Orc FileFormat
URL: https://github.com/apache/spark/pull/23491
 
 
   ## What changes were proposed in this pull request?
   
   Currently the following queries will lead to wrong Hive Serde:
   ```
   df.write.format("org.apache.spark.sql.execution.datasources.parquet.ParquetFileFormat").saveAsTable(..)
   ```
   
   ```
   df.write.format("org.apache.spark.sql.execution.datasources.orc.OrcFileFormat").saveAsTable(..)
   ```
   
   This minor PR is to fix the mapping. 
   It is also helpful for file data source V2 migration since canonical names are used when falling back to V1 is used.
   
   ## How was this patch tested?
   
   Unit test.
