Ship it! One more minor comment. Otherwise, LGTM! Thank you! trunk/src/org/apache/pig/backend/hadoop/executionengine/tez/optimizers/ParallelismSetter.java <https://reviews.apache.org/r/23787/#comment85465> I think you can do- private int estimateParallelism(TezOperPlan tezPlan, TezOperator tezOp) throws IOException { TezParallelismEstimator estimator = conf.get(...) ... } and on the caller side- parallelism = estimateParallelism(mPlan, tezOp); - Cheolsoo Park On July 25, 2014, 12:19 a.m., Daniel Dai wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
