Jeremy Beard commented on CRUNCH-372:
-------------------------------------
I want to use it for Oozie, yes. I don't know enough about the workings and
usage of delegation tokens in Hadoop to suggest how Crunch should best handle
this.
> 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?
