[Kuldeep Mishra]

Hi,
   While I creating counter column family a extra column is being added
what I do ?
Table creation script
 CREATE TABLE counters (
  key text,
  value counter,
  PRIMARY KEY (key)
 ) WITH COMPACT STORAGE

after describing column family I am getting following
CREATE TABLE counters (
  key text,
 * column1 text,*
  value counter,
  PRIMARY KEY (key,* column1*)
) WITH COMPACT STORAGE AND
  bloom_filter_fp_chance=0.010000 AND
  caching='KEYS_ONLY' AND
  comment='' AND
  dclocal_read_repair_chance=0.000000 AND
  gc_grace_seconds=864000 AND
  read_repair_chance=0.100000 AND
  replicate_on_write='true' AND
  compaction={'class': 'SizeTieredCompactionStrategy'} AND
  compression={'sstable_compression': 'SnappyCompressor'};

extra column column1 is added

Please help
