----------------------------------
Summary: [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.
