You should be able to create your own account in Apache JIRA. https://issues.apache.org/jira/login.jsp and sign-in.
After that you should be able to create the JIRA. You should use the project “Ranger". You won’t have permission to assign the owner, but it is fine.

Makes sense as the properties are available on every node. I configured the HDFS plugin with Velmurugan’s suggestions and this has worked. There is one warning on the xa_portal: WARN org.apache.hadoop.hdfs.DFSUtil (DFSUtil.java:689) - Namenode for tatooine remains unresolved for ID nn2. Check your hdfs-site.xml file to ensure namenodes are configured properly. Is this just because nn2 is currently the stand by node? Thanks Velmurugan & Bosco. From: Don Bosco Durai [mailto:bo...@apache.org] Sent: 16 June 2016 08:16 To: user@ranger.incubator.apache.org Subject: Re: HDFS Plugin - Unable to get listing of files for directory [/] from Hadoop environment Sorry to hijack the thread… Since it is common practice and sometimes required to have the HDFS properties be available on each node. Should we consider just loading the HDFS related properties directly from the HDFS properties file? In this way, we only need to provide to take the path to the HDFS folder? Dale, please confirm if this works for you.

Only resource lookup is not available during failover cases, until the repo config is updated. For HA configuration to work, need to add the below properties in repo config (I.e. additional entries in the advanced section). They can be copied from hdfs-site.xml. dfs.nameservices = <ha_name> dfs.ha.namenodes.<ha_name> = <nn1,nn2> dfs.namenode.rpc-address.<nn1> = <nn1_host:8020> dfs.namenode.rpc-address.<nn2> = <nn2_host:8020> dfs.client.failover.proxy.provider.<nn2> = org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider From: Dale Bradman <da...@profusion.com> Reply-To: "user@ranger.incubator.apache.org" <user@ranger.incubator.apache.org> Date: Wednesday, June 15, 2016 at 10:51 AM To: "user@ranger.incubator.apache.org" <user@ranger.incubator.apache.org> Subject: RE: HDFS Plugin - Unable to get listing of files for directory [/] from Hadoop environment That did not work. It works when I set: Hadoop.rpc.protection = - Then in HDFS plugin: Namenode URL = hdfs://hdpmaster01:8020 RPC Protection Type = Authentication The above works. It seems it is the HA configuration that is a problem. Will it work with NameNode HA? Is there any risk for it not being configured to HA? Thanks.

Any ideas as to why this is not working? Everything seems consistent. 2. Does the rangerrepouser have to be set up on the Ranger Admin server? It is visible on Ranger UI but is only synchronised with my edge node and not the Admin server 3. Does it matter that the namenode and secondary namenode are pointing to the same Kerberos principal? Doesn’t work if I point them to their respective principals either. Thanks, Dale
