[SPARK-8508] [SQL] Ignores a test case to cleanup unnecessary testing output until #6882 is merged

[liancheng]

Currently the test case for SPARK-7862 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 #6882. This PR ignores this test case temporarily until #6882 is merged.

@chenghao-intel@zhichao-li I think this change should be safe, but would you mind to help confirming?

Oh, sorry @liancheng actually I've created a PR for this fixing #6882.
If the output size is too small, we couldn't guarantee the deadlock would happen(in unit test), that's why we set it as 100000.

[liancheng]

I see. Since your fix is on the way, I'll just ignore this test temporarily until yours is merged.
