Julien Le Dem commented on PIG-3741:
------------------------------------
Ideally each store would get its own config object, but that would be a major
refactoring.
In the meantime, this looks like a good improvement to me.

> Currently, Utils.setTmpFileCompressionOnConf(pigContext, conf); is invoked
> for every job. In case of Seqfile, this api sets mapreduce params on conf to
> assist SequenceFileInterStorage. However, as a side effect, this might change
> the behavior of other storers due to these mapred properties. This api should
> only be called for jobs with intermediate storage.
