Impala无法删除外部表。

Question

我创建了一个外部表，路径错误（不存在）：

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';

而且我无法删除表格：

[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

那么如何解决这个问题呢？谢谢。

你能改变位置吗？ALTER TABLE name ds_user_id_csv SET LOCATION '{new location}'; - David דודו Markovitz

非常感谢！我已更改位置，最终已删除。@Dudu Markovitz - Geek2Sages
