@cduby Sorry for posting to this closed issue. I'm interested to know if you were truly able to deploy this way though. I have never done a Cloudbreak installation to Openstack with Isilon, so I'd love to find out more about what you did.

I'd like to add a point of clarity for Dell EMC Isilon. In Isilon's OneFS operating system we have implemented the server (NameNode, DataNode) half of HDFS. A solution with Isilon still requires client systems (eg, CentOS) that have the HDFS Client installed. HBase would be installed on those systems with the HDFS client. HBase cannot be installed on OneFS and run in standalone mode. It could be installed in standalone mode on another system that used a mount or other path to store data on OneFS. But that would not be the same as running HBase on OneFS.

@jss shouldn't that be mentioned in one of the two docs then? Eg, http://docs.hortonworks.com/HDPDocuments/Ambari-2.4.0.1/bk_ambari-views/content/configuring_your_cluster_for_files_view.html That doc specifically says "4. Save the configuration change and restart the required components as indicated by Ambari." It should say "and HiveServer2 in order to use Hive View".

I'm configuring Ambari Views with Kerberos. After setting the proxyusers described in the Ambari Security Guide, I'm prompted to restart several services (HDFS, Yarn, Mapreduce, HBase, Oozie I believe). However, Hive View will not launch, saying that the necessary proxyuser configurations are not present. HiveServer2 apparently looks at core-site.xml on process start and then refers back to that for the proxyuser check. Restarting HiveServer2 resolves the issue. Clearly HiveServer2 is sensitive to proxyuser configuration, so I suggest adding it to the list of components that are prompted for restart in Ambari. I've checked this in Ambari 2.2.2 and 2.4.1.

Thank you, I was able to find it on a system with successful creation. This helped me very much. In the "Restart NameNode" in restarting HDFS services after changing the plugin setting to Enabled. 2016-10-07 08:38:32,458 - Ambari admin user creation successful.
2016-10-07 08:38:33,148 - Repository created Successfully
2016-10-07 08:38:33,148 - Hdfs Repository created in Ranger admin
2016-10-07 08:38:33,149 - File['/usr/hdp/current/hadoop-client/conf/ranger-security.xml'] {'content': InlineTemplate(...), 'owner': 'hdfs', 'group': 'hadoop', 'mode': 0644}

I have a cluster that did not create a default service instance for HDFS in Ranger. On others, a service instance was created when I enabled the HDFS plugin and restarted services in Ambari. I can't find anything in the Ambari Server logs or Ranger logs hinting that communication between them failed. Where should this be logged? Do I need to turn on debug logging for that service? (I'm using Ambari 2.4 / HDP 2.5 / Ranger 0.6)

@Timothy Spann An updated, clearer guide was recently published by EMC which walks through installation of Hortonworks HDP and Isilon OneFS together. It is currently as of OneFS 8.0.0.x with HDP 2.4.x. Here it is, the EMC Isilon OneFS with Hadoop and Hortonworks Installation Guide: http://www.emc.com/collateral/TechnicalDocument/docu71396.pdf
