Robert Kanter updated OOZIE-1172:
---------------------------------
Description:
If a user tries to use a Java action (so they've written their own Java main
method) on a Kerberos-enabled cluster it will fail because they need to
propagate the delegation token like this (taken from the MapReduce action):
{code}
// propagate delegation related props from launcher job to MR job
if (System.getenv("HADOOP_TOKEN_FILE_LOCATION") != null) {
jobConf.set("mapreduce.job.credentials.binary",
System.getenv("HADOOP_TOKEN_FILE_LOCATION"));
}
{code}
We should document this somewhere.
