@Geoffrey Shelton Okot Sorry for the delay. HDP cluster is 2.6.1 and is kerberized. I've also install on it Ranger and Ranger KMS. My Os is Ubuntu 14.04. I've detailly explained my question here: https://community.hortonworks.com/questions/147826/failed-to-access-filesystem-root-through-hue-ui.html

@Jay Kumar SenSharma I've a question which is quite opposite to this. I removed kerberos completely from ambari but when I tried to restart the services throws error some. Checked logs and found that it's failing due to performing 'kinit". My question is since I removed kerberos it's not supposed to generate ticket automatically. There's some configuration which is triggering this. Can you help on this issue. Below is error when I tried to restart services. File "/usr/lib/ambari-agent/lib/resource_management/core/shell.py", line 102, in checked_call tries=tries, try_sleep=try_sleep, timeout_kill_strategy=timeout_kill_strategy) File "/usr/lib/ambari-agent/lib/resource_management/core/shell.py", line 150, in _call_wrapper result = _call(command, **kwargs_copy) File "/usr/lib/ambari-agent/lib/resource_management/core/shell.py", line 303, in _call raise ExecutionFailed(err_msg, code, out, err) resource_management.core.exceptions.ExecutionFailed: Execution of 'kinit -kt /etc/security/keytabs/smokeuser.headless.keytab ambari-qa-hwx_tvx@FHILLS.LOCAL;' returned 127. bash: kinit: command not found

@Robert Levas Thank you for your detailed explanation. With these details, i've resolved my issue. It was a problem in my kadm5.acl.

@raouia Ambari Agent can currently point to Only One Ambari Server at a time. You can see the [server] section of agent file "/etc/ambari-agent/conf/ambari-agent.ini" Example: [server] hostname=ambari1.hortonworks.com . Currently it is Manual: All the agents "/etc/ambari-agent/conf/ambari-agent.ini" file need to be manually updated to point to the Failover Ambari Server Hostname and then agents needs to be restarted so that based on the new entry for [server] Ambari Server new Host, the agents can communicate. . Although there are some improvement JIRA opened for the same (for future releases): https://issues.apache.org/jira/browse/AMBARI-17126 . Regarding your queries: 1- How to point an ambari-agent to 2 ambari-servers? >>>>> "/etc/ambari-agent/conf/ambari-agent.ini" file need to be manually updated to point to the Failover Ambari Server Hostname and then agents needs to be restarted. 2. Is it possible to mention multiple hostnames in /etc/ambari-agent/conf/ambari-agent.ini? >>>>> No currently you can define only one ambari-server hostname in the ambari-agent.ini file. 3. How can i use Zookeeper to negotiate this? >>>>> Currently it is not designed. Ambari Server does not use Zookeeper for communication with agents / other ambari servers. 4- What is the solution to use heartbeat between the 2 ambari-servers? Any suggestion? >>>>>> Ambari Agents sends heartbeat messages to Ambari Server. But currently there is no feature available inside ambari server to send/advertise heartbeat messages to other ambari servers. .

@raouia Please check the following: https://stackoverflow.com/questions/44217654/how-to-recover-zookeeper-from-java-io-eofexception-after-a-server-crash The above lists few solutions you can take to resolve this problem. HTH

Not sure why this comment went all the way to the top. In case you have missed, I am pasting it here again - "Still not very sure if this is what you need, but this might help - In Ambari go to YARN configs -> Advanced yarn-site -> set yarn.resourcemanager.max-completed-applications to 50"

@Jay SenSharma Thank you for your pertinent explanation. Now, i found a way to change the default username through the DB.
