Description

orc_merge_diff_fs.q and orc_llap.q are slow (350.487s and 290.877s respectively). We can move orc_merge_diff_fs.q to MiniLlap as we are testing merge across filesystems and there are several orc merge tests for mr. orc_llap.q seems to be creating a lot of temp tables and running sum(hash) againsts which seems to be slow.
