> Key: OOZIE-1871
> URL: https://issues.apache.org/jira/browse/OOZIE-1871
> Project: Oozie
> Issue Type: Improvement
> Components: security
> Affects Versions: trunk
> Reporter: Robert Kanter
> Assignee: Robert Kanter
>
> Currently, Oozie prepares a configuration for the action to use when
> launching MR jobs. Oozie also provides an environment variable with the
> location of the tokens file. It is up to the action's Main to:
> # Load the Configuration
> # Get the location of the Token file
> # Propagate the token file to the loaded Configuration
> # Pass the Configuration to the CLI/MR Job/etc
> This isn't too much of a problem for most actions because we handle this for
> the user, but for the Java action, it's 4 not-obvious steps. We should
> investigate if we can make this one step by having the Configuration prepared
> by the Oozie server already have the token file propagated to it; then
> actions would have 2 steps:
> # Load the Configuration
> # Pass the Configuration to the CLI/MR Job/etc
> And the tokens would be handled automatically.
> We'd still have to provide the environment variable for backwards
> compatibility and flexibility reasons though.
