[SPARK-8508] [SQL] Ignores a test case to cleanup unnecessary testing…

… output until apache#6882 is merged

Currently [the test case for SPARK-7862] [1] writes 100,000 lines of integer triples to stderr and makes Jenkins build output unnecessarily large and it's hard to debug other build errors. A proper fix is on the way in apache#6882. This PR ignores this test case temporarily until apache#6882 is merged.
