@Neha G Can you copy me the commands you used, just to be sure. Is it a single node cluster? And always include the details to error stack .

@Neha G The problem is that your HDFS is Safe mode do this to resolve the issue As root switch user to hdfs # su - hdfs Then # hdfs dfsadmin -safemode leave Then try restarting the namenode it should start successfully

@ilia kheifets revert justmeans get back to me I have just downloaded an Ubuntu 16.0.4 let me try it out. The ambari-agent can be installed NOT only when using non-root but if you don't have passwordless configuration between the nodes. # apt-get install ambari-agent Give me some time

@ilia kheifets I don't see your updated thread though I have just received your update email. So you are still encountering the same problem. What document did you use, if you have one can you share it. Did you run the below on all the 3 nodes # apt-get install ambari-agent Can you confirm that this directory exists /var/lib/ambari-agent/data/output-106.txt Please revert

@ilia kheifets Its unfortunate we didn't drill down to resolve the issue but always remember to also install the ambari-agent on the Ambari server! Keep me posted so I won't install and ubuntu 14 to resolve your problem.

@ilia kheifets Curious though did you install ambari-agent on the ambari server too? If you didn't please do that and edit /etc/ambari-agent/conf/ambari-agent.ini to point to the new host. [server] hostname={Ambari-server_FQDN} url_port=8440 secured_url_port=8441 Please le me know before I build an environment to reproduce your issue!

@ilia kheifets What is your cluster size? what error especially are you experiencing? Once you respond, I never experience such a problem n Ubuntu, will build a single node cluster and try to reproduce your error.

Shelton · ‎10-15-2017

@ilia kheifets Sorry to hear you are encountering all these problems. Could you tell me the HDP,Ambari and OS type and version you are trying to install. I will try to guide you.

@tsharma Can you attach the following files in here - krb5.conf, - kdc.conf and - kadm5.acl. What is your AD Domain? Did you import the AD cert? self signed or CA ?

Shelton · ‎10-13-2017

@tsharma Can you have a look and this HCC doc and get back to me. I think that's what you intend to implement. Create MIT KDC in the Hadoop cluster to manage service principals while using a one-way trust to allow AD users to utilze the Hadoop environment seamlessly
