------------------------------------------
This issue is related to AMBARI-8658
> Value of fs.defaultFS predefined in GlusterFS stack doesn't make sense from
> GlusterFS perspective
> -------------------------------------------------------------------------------------------------
>
> Key: AMBARI-8468
> URL: https://issues.apache.org/jira/browse/AMBARI-8468
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server, stacks
> Affects Versions: 1.6.1
> Environment: HDP 2.1 on RHEL 6 with 2.1.GlusterFS stack.
> Reporter: Martin Bukatovic
> Priority: Minor
> Labels: glusterfs, hcfs
>
> Default value of {{fs.defaultFS}} property as defined in {{core-site.xml}} of
> {{2.1.GlusterFS}} stack is not valid from GlusterFS perspective.
> {code:xml|title=from
> 2.1.GlusterFS/services/GLUSTERFS/configuration/core-site.xml}
> <property>
> <name>fs.defaultFS</name>
> <value>glusterfs:///localhost:8020</value>
> </property>
> {code}
> Leaving the current default value there may create problems for some use
> cases.
> Eg. Hive has a problem with that. Or see for example traceback from Ambari
> itself:

> The obvious fix of this would be to remove the hostname and port from the
> default value, so that it would be just {{glusterfs:///}}.
> The problem is that this can't be done without consequences: some pre-install
> scripts would have a problem with that (because we share/reuse code with HDFS
> there).
> Current workaround is to manually change the value after installation, which
> is
> hardly suitable solution from the long term perspective.
> To sum it up: in current Ambari, we can't ship valid default configuration
> in GlusterFS stack without breaking pre-install scripts at the same time.
> Since this may be usefull for any HCFS (Hadoop Compatible File
> System), not just GlusterFS, I propose to change the code in ambari so that
> any HCFS can have valid configuration in the configuration templates without
> breaking given HCFS or Ambari scripts itself. This would make possible to have
> reasonable value of {{fs.defaultFS}} in GlusterFS stack.
