帕拉不能刪除外部表

Question

我創建一個外部表有錯誤（不存在）的路徑：

create external table IF NOT EXISTS ds_user_id_csv 
(
    type string, 
    imei string, 
    imsi string, 
    idfa string, 
    msisdn string, 
    mac string 
) 
PARTITIONED BY(prov string,day string) 
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' 
stored as textfile 
LOCATION 'hdfs://cdh0:8020/user/hive/warehouse/test.db/ds_user_id'; 

我不能刪除該表：

[cdh1:21000] > drop table ds_user_id_csv 
     > ; 
Query: drop table ds_user_id_csv 
ERROR: 
ImpalaRuntimeException: Error making 'dropTable' RPC to Hive Metastore: 
CAUSED BY: MetaException: java.lang.IllegalArgumentException: Wrong FS: hdfs://cdh0:8020/user/hive/warehouse/test.db/ds_user_id, expected: hdfs://nameservice1 

那麼如何解決這個？謝謝。

使用以下命令來更改位置

ALTER TABLE name ds_user_id_csv SET LOCATION '{new location}';
