----------------------------------
Description: Calculate the value of parallism for spark mode like what
org.apache.pig.backend.hadoop.executionengine.tez.plan.optimizer.ParallelismSetter
does. (was: Now the parallism value is always 1 in current spark job, this
will cause the we only have 1 partition in HashPartitioner in shuffle process.
see
[code|https://github.com/apache/pig/blob/spark/src/org/apache/pig/backend/hadoop/executionengine/spark/converter/JoinGroupSparkConverter.java#L90].)
