Rohini Palaniswamy commented on PIG-2405:
-----------------------------------------
I think we should avoid changing to LinkedHashMap. Recently, for a different
project for test result comparison where the order was required we moved from
LinkedHashMap to TreeMap because the order of insertion into LinkedHashMap was
different in jdk7 and LinkedHashMap did not work because of that to compare
golden files. That might not be the case here because we insert iterating over
an array. But would still prefer sorting the test results when comparing
instead of changing code to use LinkedHashMap or TreeMap.
