Hi experts
I have 3 nodes hadoop kerberized cluster. But while i am opening view i am getting below error:
SIMPLE authentication is not enabled. Available:[TOKEN]
Below is the solution i came across as per the link.
https://community.hortonworks.com/questions/7896/simple-authentication-is-not-enabled-availabletoke....
As per the above solution i have made 2 changes:
"hadoop.security.authentication" to "simple" in the file /etc/hadoop/conf/core-site.xml in ambari.
'hive.server2.authentication' is set to 'None'
But while i am able to open the views but node managers and datanodes gives error to kerberos..as below:
2017-01-05 16:12:22,661 WARN authorize.ServiceAuthorizationManager (ServiceAuthorizationManager.java:authorize(119)) - Authorization failed for yarn (auth:SIMPLE) for protocol=interface org.apache.hadoop.yarn.server.api.ResourceTrackerPB, expected client Kerberos principal is nm/hdpdn1.hadoop.com@HADOOP.COM

Please help me to have kerberize cluster and views.
