[jira] Created: (PIG-1001) Generate more meaningful error message
when one input file does not exist
Generate more meaningful error message when one input file does not exist
-------------------------------------------------------------------------
Key: PIG-1001
URL: https://issues.apache.org/jira/browse/PIG-1001
Project: Pig
Issue Type: Bug
Affects Versions: 0.4.0
Reporter: Daniel Dai
Fix For: 0.6.0
In the following query, if 2.txt does not exist,
a = load '1.txt';
b = order a by $0;
c = load '2.txt';
d = order c by $0;
e = join b by $0, d by $0;
dump e;
Pig throws error message "ERROR 2100: file:/tmp/temp155054664/tmp1144108421 does not exist.", Pig should deal with it with the error message "Input file 2.txt not exist" instead of those confusing messages.

---------------------------------
Hi, Nigel,
Since this patch is all about error message and user experience, so it is hard to write a unit test case for that. I tested it manually with the following situations:
1. All jobs are successful
2. One complete failed job, and we stop launching dependent jobs
3. Two independent job, one fail, with and without -F option
All of those give us desired error messages.

[jira] Commented: (PIG-1001) Generate more meaningful error message

Posted by "Alan Gates (JIRA)" <ji...@apache.org>.

Alan Gates commented on PIG-1001:
---------------------------------
I have a question on this code in JobControlCompiler.updateMROpPlan:
{code}
for (Job job : completeFailedJobs) // remove all subsequent jobs
{
List<MapReduceOper> fifo = new ArrayList<MapReduceOper>();
fifo.add(jobMroMap.get(job));
while (!fifo.isEmpty())
{
MapReduceOper mro = fifo.remove(0);
List<MapReduceOper> succs = plan.getSuccessors(mro);
if (succs != null)
fifo.addAll(succs);
plan.remove(mro);
numRemoved++;
}
}
{code}
If we have a dependency graph like: A->B->C and A fails, won't the above code
only remove B and not C? OperatorPlan.getSuccessors() only gets immediate
successors, not all successors. I think you want OperatorPlan.trimBelow()
instead.

Daniel Dai commented on PIG-1001:
---------------------------------
Change the error handling for map-reduce jobs. Changes are:
1. If one job complete fail (If we have only one store and that job fail), then we do not start all dependent map-reduce jobs
2. Before, we do not report error message of MR job with temporary store. It is possible that we miss the root cause of the entire script. So we instead print error message of all MR jobs we kick off. With the change of not starting dependent map-reduce jobs, hopefully only the error message of the MR job causing the problem printed out.
3. Change the way we report error message when "-F" is on. Before, we only report "fail to produce xxxx", now we print out the error message that cause the problem.

---------------------------------
Hi, Alan,
The code do remove B and C. It uses fifo to achieve that to avoid recursion. But you reminds me that we have trimBlow(). We should use trimBlow() instead of implementing a duplicate logic.

Also, please provide a justification for why there is no unit test, then describe how you DID test it before you uploaded the patch.
