stczwd opened a new pull request #27644: [SPARK-30868][SQL] Throw Exception if 
runHive(sql) failed
URL: https://github.com/apache/spark/pull/27644
 
 
   ### Why are the changes needed?
   At present, HiveClientImpl.runHive will not throw an exception when it runs 
incorrectly, which will cause it to fail to feedback error information normally.
   Example
   ```scala
   spark.sql("add jar file:///tmp/not_exists.jar")
   spark.sql("show databases").show()
   ```
   /tmp/not_exists.jar doesn't exist, thus add jar is failed. However this code 
will run completely without causing application failure.
   
   
   ### Does this PR introduce any user-facing change?
   No.
   
   ### How was this patch tested?
   add new suite tests
