tpch/q15_top_supplier sporadic test failure #491

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
It seems after merging the fix of issue 460, the test case 
tpch/q15_top_supplier sporadically fails. When it fails, the query won't return 
any results with no exception thrown.

What logging level you are using?   You need to change the logging.properties 
in eclipse to see the exceptions.

I have set that to FINE, no exception is thrown upon failure.

Latest update from Sattam and me:  the join in the query checks for equality of 
two doubles, however the double value is an aggregated value.  It used to not 
show up because we only have 2 partitions in our tests,  $a+$b always equals to 
$b+$a;  but now we have 4 partitions, different aggregation order produces 
different doubles.
