Hello, I am trying to enable Kerberos on a cluster of Ubuntu 16.04.3 LTS servers. All of the nodes are already joined to a Windows domain. I used PowerBroker for that. Is it still possible to turn on Kerberos for the cluster when they are already joined to a domain? I am using the MIT KDC since our corp office is not willing to deal with the ldaps. Whenever I try to turn kerberos on I get the error that it fails to find the KDC for the realm. However, it is showing my Windows domain and not the realm that I made. I may be way off since I am still getting to know kerberos, but any help would be appreciated

I uninstalled the plugin and ranger. Then, reinstalled on a different node. Now everything is working.

Well I am not sure if that really applies to my situation. For example, I can add a user to the ranger pollicy and the ranger permissions work, but if I add a group instead it does not work.

I have successfully setup Ranger LDAP sync. I can see all users and mapped groups in Ranger. I also have added my machines to our domain and I am able to see the group mappings from active directory by typing hdfs groups username. However, when I try to add an AD group to an HDFS folder through ranger the users in that group are still denied. Any suggestions?

I have restarted all services and refreshed the browser. I even turned on the YARN plugin and that showed up just fine in Ranger.

Hello, I enable the Ranger plugin for HDFS, but a Policy does not show up in Ranger. Are there any logs that I can look at to see why this is happening or is it a known issue?

After posting this I did reconfigure Nifi and was able to get it to copy all of the data (java heap size issue). The data sizes could vary. Whatever we get from clients. The job I am copying right now is over 600GB.

We have large data folders sitting on Windows shares that we would like to replicate to HDFS for processing. I have tried NFS, but it is too slow. I have tried Nifi and it works much better, but I still experience issues. For example, the listfile processor takes so long to run and frequently errors out/crashes Nifi. Is there a better way to move large preexisting data into HDFS from a remote source using Nifi?

Sorry, I should have clarified this some more. I am currently using ListFile, FetchFile, and PutHDFS. Do the same settings apply?

Is there a way to copy and retain recursive folder structure using Nifi? I am able to copy individual files, but it would be great to be able to copy subfolders.

We are looking for a way for our users to move large data files into the hdfs for processing. I am still new to ambari/hadoop so I am not exactly sure what to go with. I have setup the NFS gateway and have been able to transfer data that way, but I am wondering if there is a better way possibly. Once everything is tested we will be moving it to an active directory structure so whatever upload method we go with has to work with that style of permissions.
