-------------------------------------

             Summary: Show a directional error message for unsupported Hive Metastore versions
                 Key: SPARK-25893
                 URL: https://issues.apache.org/jira/browse/SPARK-25893
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Dongjoon Hyun


When `spark.sql.hive.metastore.version` is misconfigured, we had better give a directional error message.

*BEFORE*
{code}
scala> sql("show databases").show
scala.MatchError: 2.4 (of class java.lang.String)
{code}

*AFTER*
{code}
scala> sql("show databases").show
java.lang.UnsupportedOperationException: Unsupported Hive Metastore version (2.4). Please set spark.sql.hive.metastore.version with a valid version.
{code}
