My suspicion will be the the inventory x catalog_sales x warehouse join - assuming the column statistics are present and valid. If you could send the explain formatted plans and swimlanes for LLAP, I can probably debug this better. https://github.com/apache/tez/blob/master/tez-tools/swimlanes/yarn-swimlanes.sh Use the "submitted to <appid>" in this to get the diagram.
