create a hive table: always a tab space before each line

[Richard]

hi there

I have a problem with creating a hive table.
no matter what field delimiter I used, I always got a tab space in the head of 
each line (a line is a record).
something like this:
\t f1 \001 f2 \001 f3 ...
where f1 , f2 , f3 denotes the field value and \001 is the field separator.


here is the clause I used 
35 create external table if not exists ${HIVETBL_my_table}
 36 (
 37 nid string, 
 38 userid string, 
 39 spv bigint, 
 40 sipv bigint, 
 41 pay bigint, 
 42 spay bigint, 
 43 ipv bigint, 
 44 sellerid string, 
 45 cate string
 46 )
 47 partitioned by(ds string)
 48 row format delimited fields terminated by '\001' lines terminated by '\n'
 49 stored as sequencefile
 50 location '${HADOOP_PATH_4_MY_HIVE}/${HIVETBL_my_table}';


thanks for help.
