@Sunile Manjee - Thanks for the info, I'm aware that we can do this using API, as @John Martin wanted to do this while installing HDP cluster hence suggested to put in configs section of ambari blueprint.

@russ stevenson If you don't Ambari to manage your krb5.conf then as per below screenshot, you can turn off "Manage Kerberos client krb5.conf" option. Login to Ambari --> Goto Kerberos --> Goto config --> Turn off "Manage Kerberos client krb5.conf" Regarding commented entries - I'm not too sure why it is commented, if I change encryption type via Ambari then also it will be commented. Adding few Ambari experts in this thread. @vpoornalingam / @ctam Note - I found this bug though - https://issues.apache.org/jira/browse/AMBARI-14001

@John Martin - If you are going to use blueprint then I believe mentioning port in the configuration is the only option.

@Raja Sekhar Chintalapati It's not because of SPNEGO, its because, once you get authenticated to KDC, you get initial ticket called TGT, using TGT further authentication happens to get Service level ticket. If you want to decide which user can access what then probably you are looking for authorization and Rager is the solution for you. Note - SPNEGO provides a mechanism for extending Kerberos to Web applications through the standard HTTP protocol. Please do let me know if you need any further help.

@John Martin You can go to each service configuration in Ambari UI and change the port number. For example for Kafka, see below screenshot

@Facundo Bianco Did you upgrade your cluster recently? Can you please login to problematic datanode and check following? ps aux|grep -i datanode If you find any pid running the datanode process then kill it. kill -9 <pid-of-datanode> Try to start datanode with below command and let me know how it goes /usr/hdp/current/hadoop-client/sbin/hadoop-daemon.sh start datanode

@jami samrat Can you please try increasing memory and see if it helps? Do you see any error when resource manager process is starting or its just stuck at that point? You can also try <ctrl>+c when it is stuck to see if its going to next step.
