Martin Bukatovic commented on BIGTOP-1307:
------------------------------------------
Thanks Jay, I will try your gradle runner of BIGTOP-1222 soon.
So far I searched for exceptions in the TestCLI output logs and find out that
there was an error on my side: I was running the TestCLI under user bigtop,
which make large number of test cases fail even though the case itself doesn't
need hdfs privileges (likely because it messed with a test environment which
doesn't anticipate non-hdfs user). After rerun under hdfs user, the number of
failing cases (in total) dropped from 163 to 103 (20%). That said the test case
#1 is still failing (in the same way as shown in the description of this JIRA),
so issue with 'No such file or directory' error was not fixed by this.

> I manually checked 5 other cases with the same result: when the testcase is
> done
> manually, it works without any problems.
> Moreover I rerun all TestCLI cases 5 times, and the set of failed cases
> was always the same.
> Have anybody seen similar behaviour? I have executed TestCLI cases via wrapper
> which sets system classpath instead of maven defined enviromnent. Can this
> caused the issue, or is it likely that the problem is the bigtop tests? Also
> feel free to propose a way to debug this further.
