Description
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
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.
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.
