   ### Describe the bug
   
   Found this bug when fixing Spark SQL test failures for #651.
   
   We use Java Arrow stream reader to reads Arrow-format shuffle data. But if 
there is struct vector with duplicate field name, Java Arrow will throw the 
following error:
   
   ```
   [info]   Cause: org.apache.spark.SparkException: Job aborted due to stage 
failure: Task 1 in stage 311.0 failed 1 times, most recent failure: Lost task
