Re: Ambari 2.0 Kerberos Activation - Failed to create keytab

Hi Rob, thank you very much. I wasn't aware Ambari is running as non-root as I always started Ambaris as root user. I changed the user setting in ambari.properties and was able to activate kerberos. Is there already a date for the Ambari Update to be availabe? Best regards Frank Am 18.04.

Re: Ambari 2.0 Kerberos Activation - Failed to create keytab

Hi FrankŠ It seems like Ambari is running as ambari-server, not root. This isn¹t typically an issue, but in this case the problem from https://issues.apache.org/jira/browse/AMBARI-10266 is coming into play. The solution will be in the next releases of Ambari (2.0.1 and 2.1), but for now it appear

Re: Ambari 2.0 Kerberos Activation - Failed to create keytab

Hi Frank, Can you check to see if /var/lib/ambari-server/data/tmp/ exists on the Ambari server host? If so, what permissions does it have? Ideally, /var/lib/ambari-server/data/tmp/ exists and all directories in the path are executable by the user that Ambari runs as. Both of these are essential

Re: Ambari Blueprint

Hi Pratik, the safest way to generate a blueprint is to actually deploy a cluster with the desired configuration (even a 3-node cluster will work). Ambari can ensure that any dependent services are also installed in the topology. Further, the blueprint also captures the configs. https://cwiki.ap
