Hi Naveen, you have the option to add local users/group or sync with LDAP: See http://docs.hortonworks.com/HDPDocuments/Ambari-220.127.116.11/bk_Ambari_Admin_Guide/content/_local_and_lda...

You can create users in LDAP and use them across machines or create users on each machine. If security is enabled, which I guess it is, then Kerberos principals need to be created and will be mapped to unix users using hadoop.security.auth_to_local property. Kerberos principals have a FQDN components sothey will be separate for each node.
I am not sure how ansible can help with this requirement. The easiest way to automate this is to use Ambari.

thanks for you response,
let's say i have a application user for application purpose ex: twitteruser how this user need to be created across all nodes? we don't want to create a user with there own name if that user left again we need to rewite the code for deployment
i already set up user in ldap so those can use in ambari access level only

It's all going to be through LDAP. Otherwise create a twitteruser on all nodes (with same password) - not recommended.
