Hemanth Yamijala commented on HADOOP-4124:
------------------------------------------
Initial proposal:
- Introduce the following CLI:
{code}
hadoop job -change-priority <job-id> <new-priority>
{code}
This can be controlled via the ADMINISTER_JOBS ACL if they are turned on.
- Make the links for changing priority appear only if
{{webinterface.private.actions}} is set to true.
Comments ?
> Changing priority of a job should be available in CLI and available on the
> web UI only along with the Kill Job actions

> Currently, a job's priority can only be changed from the job tracker web UI.
> However, it is really similar (if not as destructive) as killing a job, in
> the sense that is should not be exposed publicly. The use case for this kind
> of restriction is where Hadoop is shared in production environments by
> different users, and they should not be allowed to change another user's
> priority. At the same time, it should be possible to still change a job's
> priority in some manner, if a user is authorized to do so, and the CLI can
> provide a way to do this, along with mechanisms introduced for ACLs in
> HADOOP-3698.
