jay vyas commented on BIGTOP-1342:
----------------------------------

1) As part of this ticket, i think its our duty then to  create a JIRA for this 
in upstream hadoop - and debate there - what the solution of 
DFSConfigKeys.DFS_PERMISSIONS_SUPERGROUP_KEY is. 

2) FWIW {{+  "root_user":"hdfs"}} was what we called it in BIGTOP-1200. 

3) Sorry i will get a bigtop vm spun up tomorrow to actually run this ! Have 
been very busy this week.  


> Make TestCLI usable for both HDFS and HCFS

>                 Key: BIGTOP-1342
>                 URL: https://issues.apache.org/jira/browse/BIGTOP-1342
>             Project: Bigtop
>          Issue Type: Improvement
>          Components: Tests
>    Affects Versions: 0.8.0
>            Reporter: Martin Bukatovic
>         Attachments: BIGTOP-1342.1.patch

>
> Current TestCLI test cases are currently only runnable on HDFS.  Since the 
> most
> test cases are applicable on any hadoop filesystem, it makes sense to
> make it general in hcfs sense.
> While most test cases are hcfs generic, some cases are only applicable to 
> HDFS,
> so I propose split the current code into:
>  * general HCFS superclass (with most cases in {{testHCFSConf.xml}} file)
>  * HDFS specific subclass (with hdfs only cases in {{testHDFSConf.xml}})
> I would like to keep {{testHCFSConf.xml}} as a common base for any hadoop
> filesystem, which would require introduction of several additional variables 
> to
> catch minor differences between GlusterFS and HDFS. This should be good enough
> for other hcfs implementations as well, but I didn't tested it.
> Before proposing patch for this, it make sense to have the following resolved:
>  * BIGTOP-1341 TestCLI cleanup
>  * BIGTOP-1334 Add DFS support to TestCLI
