org.apache.pig.newplan.logical.rules.GroupByConstParallelSetter
Rule: If a LOCogroup is 'group all', set the parallelism to 1, or in general - if the group-by expression is just a constant then set parallelism to 1 LogicalExpressionSimplifier could be used to convert an expression with constants into a single ConstantExpression
