Class cast exception thrown in STRSPLIT even after casting properly
-------------------------------------------------------------------
Key: PIG-2311
URL: https://issues.apache.org/jira/browse/PIG-2311
Project: Pig
Issue Type: Bug
Affects Versions: 0.9.0
Reporter: Anitha Raju
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
