PIG-3567 LogicalPlanPrinter throws OOM for large scripts
Review Request #15565 - Created Nov. 15, 2013 and updated
Changed LPPrinter recursion to directly write to stream so that memory footprint is reduced.
Diff'ed explain plan of few existing scripts. No diffs found. I will try to submit a testcase to show that LP print of before after is same (test need not be committed).
