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) {code} 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
