Hi csguna,   Thank you for the response.  My apologies for the delayed response.     Yes, it was the class not found error. The httpclient-4.2.5.jar was placed in the application environment and restart of the services picked the required Jar and started working fine.     Thanks once again.    Cheers Nagaraj C ...

I remember this error some days back when I was trying to setup a 12 node cluster.  As far as the solution, I disabled Kerberos from all services and ensured Kerberos is not enabled across cluster (The security page shows Kerberos disabled) and redo everything to enable Kerberos for Hadoop services. It started working after this. You can try your luck.  ... View more
