Hi, I have configured hadoop-2.7.2 and oozie-4.2.0 with Kerberos security enabled.
Distcp oozie action submitted as workflow job. When running the oozie launcher, i am getting following exception. 2016-07-29 12:39:04,394 ERROR [uber-SubtaskRunner] org.apache.hadoop.tools.DistCp: Exception encountered
