David Ciemiewicz commented on PIG-786:
--------------------------------------
I think the desire for global configuration information and the notion of
environment variables might be related: PIG-602
> Default job.names - script name, load file pattern, store file pattern, sub
> task type

> Key: PIG-786
> URL: https://issues.apache.org/jira/browse/PIG-786
> Project: Pig
> Issue Type: Improvement
> Reporter: David Ciemiewicz
> Priority: Trivial
>
> I have very complex Pig scripts which are often concatenations and iterations
> of a large number of map reduce tasks.
> I've gotten into the habit of using the following construct in my code:
> {code}set job.name '$DIR/$DATE/summary.bz';
> A = load ...
> ...
> store Z into '$DIR/$DATE/summary.bz' using PigStorage();{code}
> But it would be really useful if Pig script parsing automagically set these
> job.name values.
> Ideally I'd like to have Pig just automagically construct job names for me so
> I can trace execution of multihour jobs in the HOD progress pages. Something
> like:
> {code}process-dates.pig
> A = LOAD /data/logs/daily/20090408
> ...
> STORE Z into mysummary/20090408/summary.bz
> map-group-combiner-sort{code}
> Okay you say, I could construct this kind of job.name myself if this is what
> I want.
> Well:
> 1) I'd really like to have a default constructed by Pig so I don't have to
> 2) Pig has information about what is happening that I don't have such as:
> * The name of the script passed to Pig
> * The glob expansion of the file pathname in the LOAD statement
> * The execution plan of pig that would tell me what the
> map-group-combine-sort-reduce group looks like
> * The name of intermediate STORE operations that are being performed
