Hi Benoy, Thanks for your response. Would You can also obtain kerberos tickets programatically using keytab. See http://hadoopsecurity.org/wiki/How%20to%20access%20secure%20Hadoop%20cluster%20programmatically%20using%20keytab it also work from remote client machine?
Shouldn’t it be like need to connect with remote KDC server first for kinit? Here in my case, KDC is on machine X and secured hadoop cluster is on machine Y. Please suggest.
