----------------------------------

Thanks [~sushanth]  and the "STORED AS " feature is very useful for me too.

> By default,when output hive table to file ,columns of the Hive table are separated by
^A character (that is \001).
> But indeed users should have the right to set a seperator of their own choice.
> Usage Example:
> create table for_test (key string, value string);
> load data local inpath './in1.txt' into table for_test
> select * from for_test;
> UT-01:default separator is \001 line separator is \n
> insert overwrite local directory './test-01' 
> select * from src ;
> create table array_table (a array<string>, b array<string>)
> ROW FORMAT DELIMITED
> FIELDS TERMINATED BY '\t'
> COLLECTION ITEMS TERMINATED BY ',';
> load data local inpath "../hive/examples/files/arraytest.txt" overwrite into table table2;
> CREATE TABLE map_table (foo STRING , bar MAP<STRING, STRING>)
> ROW FORMAT DELIMITED
> FIELDS TERMINATED BY '\t'
> COLLECTION ITEMS TERMINATED BY ','
> MAP KEYS TERMINATED BY ':'
> STORED AS TEXTFILE;
> UT-02:defined field separator as ':'
> insert overwrite local directory './test-02' 
> row format delimited 
> FIELDS TERMINATED BY ':' 
> select * from src ;
> UT-03: line separator DO NOT ALLOWED to define as other separator 
> insert overwrite local directory './test-03' 
> row format delimited 
> FIELDS TERMINATED BY ':' 
> select * from src ;
> UT-04: define map separators 
> insert overwrite local directory './test-04' 
> row format delimited 
> FIELDS TERMINATED BY '\t'
> COLLECTION ITEMS TERMINATED BY ','
> MAP KEYS TERMINATED BY ':'
> select * from src;
