Aniket Mokashi commented on PIG-3739:
-------------------------------------
PIG-2207 changed group of WARNINGs from PigWarning(enum) to class of udf
(string). This breaks computeWarningAggregate and hence no warning messages are
displayed on stdout. We can get list of udfs for a job from
jcc.getJobMroMap().get(job).UDFs (private->public or getter) and then iterate
over udfs and get all the counters (not ideal). Comments?
> The Warning_4 e2e test is broken in trunk

> Key: PIG-3739
> URL: https://issues.apache.org/jira/browse/PIG-3739
> Project: Pig
> Issue Type: Bug
> Reporter: Cheolsoo Park
> Assignee: Aniket Mokashi
> Fix For: 0.13.0
>
>
> This is a regression of PIG-2207.
> The Warning_4 e2e test fails because expected warning messages are not
> printed to stderr. I confirmed that the following lines are present w/o
> PIG-2207, whereas they are not w/ PIG-2207.
