Devaraj Das commented on HADOOP-8192:
-------------------------------------
One option is to make the relevant hashmaps sorted in CombineFileInputFormat,
and then fix the testcase to check the correct (and consistent) values in the
asserts. Would that fix the testcase problem? The other option is to make the
testcase more robust so that it can tolerate the fact that ordering could be
different on different JVMs.
