pig.splitCombination vs. pig.noSplitCombination vs. MapReduceOper#combineSmallSplits() ?
While looking in the MRCompiler, I noticed the following...
if (!mro.combineSmallSplits() || pigContext.getProperties().getProperty(
"pig.splitCombination", "true").equals("false"))

                conf.setBoolean("pig.noSplitCombination", true);
These are three values that SEEM like they do the same thing, but don't
quite? I don't know.
Is there a difference in what these do?
