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 ... View more

Is there a better way to move large preexisting data into HDFS from a remote source using Nifi? ... View more

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. ... View more
