Martin Bukatovic updated BIGTOP-1321:
-------------------------------------

    Attachment: 0001-BIGTOP-1321.-Check-assumptions-for-TestCLI.patch

Initial patch attached. I'm not sure if raising excpetion like that follows the 
code style, but I think that when setup fails or severe misconfiguration is 
detected, the test needs to fail with clear description without executing the 
test cases.

> TestCLI: check assumptions before the test run

>             Project: Bigtop
>          Issue Type: Improvement
>          Components: Tests
>    Affects Versions: 0.8.0
>            Reporter: Martin Bukatovic
>            Assignee: Martin Bukatovic
>            Priority: Minor

> The TestCLI test cases has some assumptions which are not checked in the test 
> code. This is a proposal to add checks for each important assumption which 
> would make some cases fail if not met. This would save us some debugging time 
> when setting up new test environment and would make this test easier to reuse.
> So far, I have identified these:
>  * the effective user must be hdfs (a root for HDFS)
>  * the HDFS trash feature must be disabled (`fs.trash.interval` should be 0)
>  * hdfs://tmp/testcli_TIMESTAMP directory has been really created
> I expect there are additional assumptions worth checking, any other ideas?
