Thanks Bosco for confirming the incompatibility between Ranger 0.5 and Hadoop 2.6. I’m going to try installing Ranger 0.4 from scratch and will get back to you if I run into any issues with that.

You can see the installation document at https://cwiki.apache.org/confluence/display/RANGER/Ranger+Installation+Guide. For HDFS authorization you shouldn’t see much difference between Ranger 0.4 and Ranger 0.5. Regarding the repo, you need to give the values from your core-site.xml. Also note, “Test Connection” is not mandatory. We can always make it work later. The main issue for you would be the the config path and libraries. Can you find out where the core-site.xml is on your Namenode? It will help to do the configuration.

I’ve gone through that thread too, the only difference being that we actually have Kerberos enabled in our Hadoop Cluster. On the ranger admin UI, under the dfs.datanode.kerberos.principalfield, what do I specify? I ask because we have multiple datanodes and the each of them have a different principal that is tied to their hostname. Also, to reiterate my original question about CDH, are there any known incompatibilities with CDH? Also, are there any known incompatibilities between Ranger 0.5.0 and hadoop 2.6.0?

Also, can you ensure the repository name you created in Ranger admin is the same one being configured for Ranger plugin?

We have been able to get the Ranger Admin portal running but cannot seem to get the Hadoop Namenode to pick up the HDFS plugin. We are following the instructions at https://cwiki.apache.org/confluence/display/RANGER/Ranger+Installation+Guide. We’ve tried both 0.5.0 and 0.4.1 after compiling the source code. I see that the name node is picking up the jar files from /usr/lib/hadoop directory and the right configuration values are injected into the xml files (hdfs-site.xml) but I don’t see the agent on my ranger admin UI. Are there any known incompatibilities with CDH versions of Hadoop? Or is there something that we’re missing? Cheers, -- Harish
