    https://github.com/apache/spark/pull/16638
  
    Here is the differences between Hive and Spark2.x as follow:
    1.Hive
    create table test(id int); --> MANAGED_TABLE
    create table test(id int) location '/warehouse/test'; -->  MANAGED_TABLE
    create external table test(id int) location '/warehouse/test'; -->  
EXTERNAL_TABLE
    create external table test(id int); -->  EXTERNAL_TABLE
    
    2.Spark2.x:
    create table test(id int); -->   MANAGED_TABLE
    create table test(id int) location '/warehouse/test'; -->  EXTERNAL_TABLE
    create external table test(id int) location '/warehouse/test'; -->  
EXTERNAL_TABLE
    create external table test(id int); -->   operationNotAllowed("CREATE 
EXTERNAL TABLE must be accompanied by LOCATION", ctx) 
    
    So,this PR follows the spark2.x‘s design rules,thanks!
