> Hi,
> The below script treats 'a' as bytearray thus throwing class cast exception at STRSPLIT
> =========
> A = load 'input.txt' using PigStorage() as (a);
> A1 = filter A by NOT (a is null);
> A1 = foreach A1 generate a as a:chararray ;
> describe A1;
> B = foreach A1 generate STRSPLIT(a);
> dump B
> =========
> Input.txt (space separated)
> =========
> a b
> =========
> Here i am casting as "a as a:chararray". If you see the output of describe it gives
> A1: {a: chararray}
> When its passed in STRSPLIT, it treats as a bytearray thus throwing the following exception
in the task logs
> =======
> WARN org.apache.pig.builtin.STRSPLIT: class cast exception at org.apache.pig.builtin.STRSPLIT.exec(STRSPLIT.java:55)
> =======
> hence giving null output at B.
> If we cast 'a' using
> =========
> A1 = foreach A1 generate (chararray)a as a ;
> =========
> it gives the correct output.
> ((a,b))
> In both the cases the describe gives 
> A1: {a: chararray}
> Regards,
> Anitha
