> count(*) on a table written by hcatstorer returns wrong result. 
> {code}
> steps to repro the issue:
> 1) create hive table
> {noformat}
> create  table ${DEST_TABLE}(name string, age int, gpa float)
>                             row format delimited
>                             fields terminated by '\t'
>                             stored as textfile;
> {noformat}
> 2) load data into table using hcatstorer
> {noformat}
> A = LOAD '$DATA_1' USING PigStorage() AS (name:chararray, age:int, gpa:float);
> B = LOAD '$DATA_2' USING PigStorage() AS (name:chararray, age:int, gpa:float);
> C = UNION A, B;
> STORE C INTO '$HIVE_TABLE'  USING org.apache.hive.hcatalog.pig.HCatStorer();
> {noformat}
