Koji Noguchi created PIG-5335:
---------------------------------
Summary: Error message from range projection completely misleading
Key: PIG-5335
URL: https://issues.apache.org/jira/browse/PIG-5335
Project: Pig
Issue Type: Bug
Reporter: Koji Noguchi
Assignee: Koji Noguchi
{code}
A = load 'input.txt' as (a0,a1,a2,a3);
B = FOREACH A GENERATE a0, a1, a2, a3;
store B into '/tmp/deleteme';
C = FOREACH A GENERATE a0, b1, a2, a3;
D = FOREACH C GENERATE a0..a2;
(end of script, no store, nothing)

Error message
{panel}
2018-04-10 10:22:33,360 \[main] ERROR org.apache.pig.PigServer - exception
during parsing: Error during parsing. Invalid field projection. Projected field
\[a0] does not exist in schema:
a0:bytearray,a0:bytearray,a2:bytearray,a3:bytearray.
{panel}
At least two issues.
# Error should be about FOREACH for C referencing non-existing field 'b1'. But
the error message is saying something about 'a0'.
# Script itself is not using relation C and D at all. It's confusing to see
errors coming out of unused relations.
