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

             Summary: Create JDBC External Table NullPointerException
                 Key: HIVE-19455
                 URL: https://issues.apache.org/jira/browse/HIVE-19455
             Project: Hive
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 3.0.0, 2.3.3
            Reporter: gonglinglei


{{JdbcSerDe.initialize}} use {{tbl.containsKey(JdbcStorageConfig.DATABASE_TYPE.getPropertyName())}} to decide whether properties is empty and whether to initialize serde. But when creating a external table
without {{hive.sql.database.type}} provided, it will throw a NullPointerException.
