Siddharth Seth commented on TEZ-2886:
-------------------------------------
bq. That's my plan initially. Given that Tez went out of its way to not use the
AM credentials, I assumed there must be some reason that was desired and am
coding up a config to request it be merged. One might argue the default should
be it merges and in the, I'm guessing rare, case that one does not want that
behavior it can be set to false.
Given we don't support multi-users, I'm also in favor of merge by default, with
an option to disable the merge.
> Ability to merge AM credentials with DAG credentials

> Project: Apache Tez
> Issue Type: Improvement
> Affects Versions: 0.7.0
> Reporter: Jason Lowe
> Assignee: Jason Lowe
>
> Currently AM credentials are explicitly kept separate from DAG credentials,
> but this can cause problems when credentials are automatically added to the
> application as part of the submission process but outside of the client's
> knowledge. We need the ability for the AM's credentials to be merged with
> the DAG credentials so DAGs can pick up important credentials that were not
> submitted by the client.
