One of my PRs compressed_skip_header_footer_aggr.q was failing with unexpected
diff. Such as:
{code:java}
TestMiniLlapLocalCliDriver.testCliDriver:62 Client Execution succeeded but
contained differences (error code = 1) after executing
compressed_skip_header_footer_aggr.q

Investigating it, it did not seem to fail when executed locally. Since I
suspected test interference I searched for the tablenames/directories used and
discovered empty_skip_header_footer_aggr.q which uses the same table names AND
external directories.
