------------------------------------
Summary: Add a way to specify a default JT/RM and NN
Key: OOZIE-2187
URL: https://issues.apache.org/jira/browse/OOZIE-2187
Project: Oozie
Issue Type: New Feature
Components: core
Reporter: Robert Kanter
Oozie is cluster agnostic, which is why we require an RM/JT and NN per action
in your workflow (or once via the <global> section). In practice, many users
use one Oozie server per cluster, so it's an extra burden for them to have to
specify this all the time. It would be convenient if we added configuration
properties to oozie-site that would let you specify a default RM/JT and NN to
use.
This way, these users could completely omit the {{<job-tracker>}} and
{{<name-node>}} fields from their workflows; as an added benefit, they can
easily update these values if they ever rename/move their RM/JT or NN. We'd of
course still allow specifying {{<job-tracker>}} and {{<name-node>}} in each
action and {{<global>}} to allow individual workflows or actions to override
the default.
