Thanks @Predrag Minovic
Indeed this is quite detailed. I've a user ambariserver and principal ambariserver/ambari_host_name@KDCRealm.com
I also verified following two properties are added in the custom core site.
PIG/Hive view, I've added following two properties in the webhcat-site.xml
Accessing the Hive View we see error.
H020 Could not establish connecton to HiveServer2_HOST:10000:org.apache.thrift.transport.TTransportException
Okay, what's the status of the Files view now? Can you now browse the files? Also try to restart ambari-server just in case.
Regarding Hive error, what's your Hive transport mode, binary or http? Only Hive view packaged with Ambari-184.108.40.206 (and I guess 2.2) supports http mode, old Ambari versions support only binary mode.
Is there any special reason you are using http Hive transport mode? [For example, Knox requires http mode.] If not, then set the transport mode to binary and Hive view should work. If you want to keep the http transport than you need Ambari-220.127.116.11 or 2.2.
@Darpan Patel Regarding NN HA support, as I mentioned above, based on our recent experience with Ambari-18.104.22.168 in a kerberized cluster, Files and Hive views support NN HA, while Pig view doesn't. I haven't had time to explore Ambari-2.2 yet.
Darpan, I have one question related to what you did. I am newbie to Kerberos. I am actually running a similar configuration, where I have AD that holds all principals. Regarding what you have said:
>>After Kerberization I created a user "ambari-user/ambari-Host_name_here@KDCRealm.com
you did this in the AD right ?
>>And also created a key tab, copied on the ambari -server machine
How did you do that? You created the keytab at the ambari-server host ? or created it in AD and somehow you copied the keytab to /etc/security/keytabs of your ambari server host ?
