Micah Whitacre commented on CRUNCH-372:
---------------------------------------
Should it always override or only if not specified in the Configuration already?
Also while you reference MR in Oozie is this request to make using Crunch in
Oozie easier or were you using it as an example and want to use it outside of
Oozie?
> Allow MRPipeline to retrieve delegation token if available

> 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?
