Subject [jira] [Created] (CRUNCH-372) Allow MRPipeline to retrieve delegation token if available
Date Mon, 31 Mar 2014 22:05:15 GMT
Jeremy Beard created CRUNCH-372:
-----------------------------------

             Summary: Allow MRPipeline to retrieve delegation token if available
                 Key: CRUNCH-372
                 URL: https://issues.apache.org/jira/browse/CRUNCH-372
             Project: Crunch
          Issue Type: Improvement
          Components: Core
    Affects Versions: 0.8.0
            Reporter: Jeremy Beard
            Assignee: Josh Wills


Delegation tokens are used when executing MR from an Oozie workflow. MR in Crunch can be manually
set to reference the token:

if (System.getenv("HADOOP_TOKEN_FILE_LOCATION") != null) {
    getConf().set("mapreduce.job.credentials.binary", System.getenv("HADOOP_TOKEN_FILE_LOCATION"));
}

However if it would be nice if this was somewhere in the API, or perhaps automatically handled?
