Dmitriy V. Ryaboy commented on PIG-2128:
----------------------------------------
I verified that external jars do work. It's a significant speedup. +1.
Please change title of jira to refer to this specific optimization so we don't
have 15 "local mode is slow" tickets as we keep chipping away at this :).
> Pig local mode is very slow.

> Since the Pig local mode implementation has been moved to Hadoop local it is
> very slow.
> We should optimize some of the steps so that it is more user friendly.
> One thing would be to skip building the jar for each job as it runs in the
> same process.
