Yin Huai updated HIVE-2206:
---------------------------
Attachment: HIVE-2206.3.patch.txt
I used "ant clean package test tar -logfile ant.log" to test all cases again
and all unknown errors are gone... There are four failures left (groupby1,
groupby2, groupby3 and groupby5). These four failures are caused by changes I
made in the method "genGroupByPlanReduceSinkOperator" in the class
"SemanticAnalyzer". So, current results should be updated. But I am not sure
how to change the correct results. Does overwrite current results with the new
results work? Or, is there anything I should do?
> add a new optimizer for query correlation discovery and optimization
