             Summary: Verification of Function-related ExternalCatalog APIs
                 Key: SPARK-16935
                 URL: https://issues.apache.org/jira/browse/SPARK-16935
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Xiao Li


Function-related `HiveExternalCatalog` APIs do not have enough verification logics. After the PR, `HiveExternalCatalog` and `InMemoryCatalog` become consistent in the error handling. 

For example, below is the exception we got when calling `renameFunction`.
