Configure Kerberos Authentication in Hortonworks Hadoop HDP 2.6.4

Configure Kerberos Authentication in Hortonworks Hadoop HDP 2.6.4

Hi Team,

 

We are using LDAP authentication to login users on Hadoop servers and submit jobs through BMC Control-M(Version 9.0.00.500)

All Hadoop service related users are local users. Ambari WebUI Login using Local Users.

We are planning to Configure Kerberos Authentication in Hortonworks Hadoop HDP 2.6.4

Could you please help me to configure it.

HDP 2.6.4

Ambari 2.6.1.5

OS RHEL 7

There are 2 ways to kerberize a cluster either MIT or AD as the KDC. In your situation, the easiest option will be to use the AD as KDC so that during the initial kerberization all existing AD users Kerberos  keytabs will be generated automatically and all subsequent users added in AD wil also trigger their keytab creation without will be trigger automatically.

 

You will need a Windows Server 2012R2 or later and quite a number of steps to achieve that. Here is a visually rich document from @Kuldeep  Setup and configure Active Directory server for Kerberos

The steps look challenging but doable also have this as a Hortonwork reference but the Kuldeep document will work like a charm.

  
hope that helps
