Description

Overall: The hive tests in test-artifacts are prone to failures from missing data sets and generally need a thorough review

When testing bigtop 0.8.0 release candidate, I found that I got some errors

I know there is a diff error in here - some kind of diff is going on , but I forgot how the actual,output,and filter are working.

In any case, I think these tests can be simplified to just grep for a output string and check error code, or else, at least add some very clear assertions as to what failures may be.
