We need pc, LoaderProcessor need to serialize it before invoking getSplit, ParallelismSetter need to set cross hint to pc. It is possible skip conf though. > On July 24, 2014, 10:33 p.m., Cheolsoo Park wrote: > > trunk/src/org/apache/pig/backend/hadoop/executionengine/tez/optimizers/LoaderProcessor.java, > > lines 73-78 > > <https://reviews.apache.org/r/23787/diff/2/?file=641130#file641130line73> > > > > Aren't these duplicate since they're set in TezDagBuilder? Am I wrong? These need to be there to make PigInputFormat.getSplits work. I verified these are minimum set. > On July 24, 2014, 10:33 p.m., Cheolsoo Park wrote: > > trunk/src/org/apache/pig/backend/hadoop/executionengine/tez/optimizers/LoaderProcessor.java, > > lines 119-122 > > <https://reviews.apache.org/r/23787/diff/2/?file=641130#file641130line119> > > > > Do we need to set these properties again here becasue I see the same > > properties are set in the payload of vertices in TezDagBuilder?
