@Madhur Thanks for the update. So I can conclude that HA must work in both the below 2 cases 1. HA must work whenever active namenode daemon goes down. 2. HA must work whenever active namenode server goes down. Please note that i am mentioning two thing i,e active namenode daemon and active namenode server

@Madhur : Thanks for the update!! Thanks for sharing links. But I am looking for answers for my below questions 1. When active namenode server is rebooted will the standby namenode will not become active? Is this something expected? Or Did the HA did not work in our cluster 2. Whether the HA is expected to work only between the active and standby namenode daemons?

HI Team, I came across an scenario where HA failed when active namenode server was rebooted. Accidentally the master node which runs active namenode got rebooted. when it got rebooted i believed the standby namenode will become active namenode and will continue the operations but standby namenode did not became active and HDFS was completely down. So my question is 1. When active namenode server is rebooted will the standby namenode will not become active? Is this something expected? Or Did the HA did not work in our cluster 2. Whether the HA is expected to work only between the active and standby namenode daemons? Thanking in Advance!!

Hi Team,
I am currently using HDP3.0 and ambari 2.7.3. I have enabled Kerberos from ambari.
KDC is installed and configured. Able to kinit and create principal.
I tried below thing,
kinit -kt /etc/security/keytabs/nn.service.keytab nn/mastern1.bms.com@BMS.COM [root@mastern1 ~]# klist -e Ticket cache: FILE:/tmp/krb5cc_0 Default principal: nn/mastern1.bms.com@BMS.COM
Valid starting Expires Service principal 06/04/2020 20:19:07 06/05/2020 20:19:07 krbtgt/BMS.COM@BMS.COM Etype (skey, tkt): aes256-cts-hmac-sha1-96, aes256-cts-hmac-sha1-96

[domain_realm] bms.com = BMS.COM

[realms] BMS.COM = { admin_server = mastern1.bms.com kdc = mastern1.bms.com }
ERROR that i see below is

Hi Team,
I Need your help where I have built single node cluster where i have enabled kerberos. Post that namenode is not starting up followed by other services.
I am currently using HDP 3.1.4 version.
my krb5.conf file looks like below
vi /etc/krb5.conf
[libdefaults] default_ream = HADOOP.COM
[realm] HADOOP.COM = { kdc = test.bms.com admin_server = test.bms.com }
[domain_realm] .hadoop.com = HADOOP.COM hadoop.com = HADOOP.COM

@Jay Kumar SenSharma I have figured it out. Thank you!! I also need to know one more thing. Using the feature Enable Service Auto start is it a safe way to configure it in Ambari in any environment? Is there any Cons having it enabled? If we enable auto start, will there be affect on service which will ask for restarting the service? Thanking in Advance!!!

Hi Team,
we have configured all the Ambari alerts to send a notification to an email id's till today. Now we are in plan to integrate the Ambari to Service Now(any ITSM) so that there is an incident open in servicenow.
Please let me know if this is possible to do? If Yes then please send me some articles/Links to refer and I can plan accordingly. Also let me know if there any challenges that we might come across.
Thanking in Advance..
