gengliangwang opened a new pull request #24369: [SPARK-27459][SQL] Revise the exception message of schema inference failure in file source V2
URL: https://github.com/apache/spark/pull/24369
 
 
   ## What changes were proposed in this pull request?
   
   Since https://github.com/apache/spark/pull/23383/files#diff-db4a140579c1ac4b1dbec7fe5057eecaR36, the exception message of schema inference failure in file source V2 is `tableName`, which is equivalent to `shortName + path`.
   
   While in file source V1, the message is `Unable to infer schema from ORC/CSV/JSON...`. 
   We should make the message in V2 consistent with V1, so that in the future migration the related test cases don't need to be modified. https://github.com/apache/spark/pull/24058#pullrequestreview-226364350
   
   ## How was this patch tested?
   
   Revert the modified unit test cases in https://github.com/apache/spark/pull/24005/files#diff-b9ddfbc9be8d83ecf100b3b8ff9610b9R431 and https://github.com/apache/spark/pull/23383/files#diff-9ab56940ee5a53f2bb81e3c008653362R577, and test with them.
