---------------------------------------
[~pallavi.rao]: The result of group has difference between mapreduce and spark
mode. A lot of unit test failures are caused by this.
I think it's better not to modify Util#checkQueryOutputs. It's better to
modify the unit test case to pass the unit test like following way:
TestMultiQuery#testMultiQueryJiraPig4480
from
{code}
......
Util.checkQueryOutputs(actualResults.iterator(), expectedResults);
.....
Util.checkQueryOutputs(actualResults.iterator(), expectedResults);
{code}
to
{code}
@Test
public void testMultiQueryJiraPig4480() throws Exception {
......
Util.checkQueryOutputsAfterSort(actualResults.iterator(),
expectedResults);
.....
Util.checkQueryOutputsAfterSort(actualResults.iterator(),
expectedResults);
}
{code}
Before we have modified a lot of this kind of cases like PIG-4276.
[~mohitsabharwal], can you give us your opinion?
