Matt Foley commented on AMBARI-8484:
------------------------------------
Turns out that the older version of Tez (0.4) erroneously required
fully-qualified paths. This was fixed for Tez (0.5.2), see TEZ-1713.
> [GlusterFS/HCFS] tez-site.xml and webhcat-site.xml should use default
> filesystem references, not explicit "hdfs:" URIs

> Key: AMBARI-8484
> URL: https://issues.apache.org/jira/browse/AMBARI-8484
> Project: Ambari
> Issue Type: Bug
> Affects Versions: 1.6.1, 1.7.0
> Reporter: Matt Foley
> Fix For: 2.0.0
>
>
> In both branch-1.6.1 and branch-1.7.0, under
> ambari/ambari-server/src/main/resources/stacks/HDP/2.1/services/TEZ/configuration/,
> the file tez-site.xml specifies the value of tez.lib.uris as:
> * <value>hdfs:///apps/tez/,hdfs:///apps/tez/lib/</value>
> This explicitly references the HDFS file system, which means it won't work
> with any other file system. It should instead read
> * <value>/apps/tez/,/apps/tez/lib/</value>
> which implicitly references the default file system specified by fs.defaultFS.
> The "hdfs:///" usage causes the only apparent difference between
> 2.1/services/TEZ/ and 2.1.GlusterFS/services/TEZ/. The complexity of
> interfacing GlusterFS and other HCFS would be decreased if the explicit usage
> of "hdfs:///" URIs was removed.
> In branch-1.6.1, a similar usage occurs in three places in webhcat-site.xml
> under
> ambari/ambari-server/src/main/resources/stacks/HDP/2.1/services/WEBHCAT/configuration/.
> The services/WEBHCAT subdirectory seems to be absent in branch-1.7.0, but
> it isn't clear why; see AMBARI-8483. If the absence is correct, then this is
> no longer an issue for webhcat-site.xml. If the absence is itself an error,
> then usage of "hdfs:///" should also be corrected for webhcat-site.xml.
