我找到了答案。代替「-2」（刺分隔符），我用「-61」分隔符接着一個子串，以除去附加的符號，類似下面

CREATE EXTERNAL TABLE IF NOT EXISTS SSSSSS ( spot_id STRING, activity_type_id STRING, activity_type STRING, activity_id STRING, activity_sub_type STRING, report_name STRING, tag_method_id STRING ) PARTITIONED BY (dt STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '\-61' LINES TERMINATED BY '\n' STORED AS TEXTFILE LOCATION 'SSSSSS';

，然後使用子串，以除去其它符號

INSERT OVERWRITE TABLE vvvvvv PARTITION (dt) SELECT spot_id STRING, substr(activity_type_id,2), dt FROM SSSSS

希望它可以幫助..
