>
> 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.
