Why is data getting converted to hex when loading from Pig?

tempReps = Load '/discovery/hbid_crd.csv' USING PigStorage(',');

STORE tempReps INTO '{hbid(HBID varchar, CRD_ID varchar, PROSPECT_IND varchar, STATUS_CODE varchar)}' USING   com.vertica.pig.VerticaStorer('ipaddress',  'database','5433','user','password');
