							 this issue is fixed. root cause is /etc/hosts on worker nodes. we had to add /etc/hosts to test another component and i did not follow the order , FQDN is not followed by ip. that was the reason RS freaked-out.

							 I've configured centrify express for AD/Linux integration. I was able to login to linux machine using windows credentials. I had setup one way trust between AD & Local MIT KDC.  [root@master2 ~]# ssh rvchinta@master2   Red Hat Enterprise Linux Server release 6.4 (Santiago)   Kernel 2.6.32-358.el6.x86_64 on an x86_64   Password:   Last login: Sat Mar  4 07:22:34 2017 from 192.168.56.22   [rvchinta@master2 ~]$ klist   Ticket cache: FILE:/tmp/krb5cc_cdc201327698_saYNYF   Default principal: rvchinta@CHRSV.COM   Valid starting     Expires            Service principal   03/04/17 10:02:32  03/04/17 20:02:32  krbtgt/CHRSV.COM@CHRSV.COM           renew until 03/11/17 10:02:32   [rvchinta@master2 ~]$    when i access hadoop components it thinks my user name is rvchinta@CHRSV.COM.  
  Any idea how to handle this? i should be rvchinta but not rvchinta@CHRSV.COM.  
  thanks
