Hi, What's the recommended way to access a secure cluster from another (both are configured to use the same kerberos realm)? For example, can I run a map-reduce job with input on a secure cluster and output on another? Do I have to change any configurations or add specific credentials for the second cluster to the UserGroupInformation object? I tried this but I keep getting "GSSException No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)".
Thanks in advance, -- Bhooshan
