Rohini Palaniswamy commented on PIG-4455:
-----------------------------------------
You might also want to set walkLeavesInOrder true in the constructor of
DependencyOrderWalker else plan can differ for different versions of jdk.
bq. for the printing mr job dependency. I didn't do it, because think it may
affect the test case of TestMRCompiler, lots of golden files need to change
Are you sure this change does not already affect golden files in
TestMRCompiler and no tests fail? It looks to me, that they will fail if the
golden files are not updated.
> Should use DependencyOrderWalker instead of DepthFirstWalker in MRPrinter

> Using DependencyOrderWalker is much better than DepthFirstWalker, and it
> would be better to also print the mr job dependency like TezGraphPrinter
