Do you think we should create a JIRA in Hadoop which indicates that there
should be a superuser parameter in the hadoop common namespace ( shouldnt own
the notion of a superuser other file systems have super users to !)
{quote}
So are you suggesting to move {{dfs.permissions.superusergroup}} from
{{hdfs-site.xml}} into something like {{hcfs.permissions.superusergroup}} in
let's say {{core-site.xml}} or even {{hcfs-site.xml}}? While I'm not sure if it
would be easy to convince Hadoop upstream about this, creating JIRA for it in
Hadoop is actually a good idea. This issue definitely deserves an official
upstream solution applicable to any Hadoop filesystem. Do we have other dfs
properties related to GlusterFS like this one?
{quote}
Can we also suggest alternative way of defining superuser for this test ? I
think its a little self-defeating to depend on an HDFS parameter when we're
trying to make the tests HCFS compliant – but i totally see why you are using
it - let me know if im missing something.

I'm using it because I need to keep HDFS compatibility, but you can redefine it
using {{hcfs.root.groupname}} property. So I would say that the patch already
provides alternative way of defining superuser. See the code:
{noformat}
supergroup = System.getProperty("hcfs.root.groupname",
conf.get(DFSConfigKeys.DFS_PERMISSIONS_SUPERUSERGROUP_KEY));
{noformat}

Does this take into account the semantics we agreed on in the BIGTOP-1200 patch
( just a quick thought).
{quote}
Well I expect that superuser and supergroup for GlusterFS run is root ( see
properties {{-Dhcfs.root.username=root -Dhcfs.root.groupname=root}} from
comment above). Or do you have something else to point out?

> 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
