Hive | Unable to create a partitioned table | ParseException

Question

I am trying to create a partitioned table from the Hive CLI,

CREATE EXTERNAL TABLE IF NOT EXISTS stocks (
   ymd             STRING,
   price_open      FLOAT, 
   price_high      FLOAT,
   price_low       FLOAT,
   price_close     FLOAT,
   volume          FLOAT,
   price_adj_close FLOAT
 )
 PARTITIONED BY (exchange STRING, symbol STRING)
 ROW FORMAT DELIMITED FIELDS TERMINATED BY ',';

But the terminal throws an exception instead "ParseException".

The error dump,

FAILED: ParseException line 10:17 cannot recognize input near 'exchange' 'STRING' ',' in column specification

Any clue what I am missing here? The syntax looks impeccable :)

Thanks

Exchange is a keyword in hive. You have to use a different name for your partition column.
