Pig 0.8 zero return code when pig script fails; also error is dumped on screen instead of logfile

I have pig script where one input directory cannot be accessed. The pig script obviously fails but the return code is zero.

A = LOAD '/user/viraj/testdata1' USING PigStorage(':') AS (ia, na);
B = FOREACH A GENERATE $0 AS id;
C = LOAD '/user/tstusr/test/' USING PigStorage(':') AS (ib, nb);
D = FOREACH C GENERATE $0 AS id;
--dump B;
E = JOIN A by ia, C by ib USING 'replicated';
store E into 'id.out';

Here is the console output:

Clearly users depending on this return code to run their workflows are affected.
