Accessing a secure cluster from another

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,
