Karam Singh commented on HADOOP-5419:
-------------------------------------
After applying the latest patch, ran some -: mapred. queue -showacls commands
and found one issue and one minor enhancement-:
Issue -:
In mapred-site.xml for queue acls if we specify user gorups instead of user
queue -showacls command gives black list in console.
E.g
Have two queue: Q1,Q2
Q1 acl: SUBMIT_JOB=u1,u2 and ADMIN_JOB=U3
Q2 acls SUBMIT_JOB= UG1(where UG1 is user group) and ADMIN_JOB=U3
Now use commad: mapred queue -showacls (with user U5 who is part of UG1 group)
It shows -:
[
Queue acls for user : U5
]
Where U5 can submit job to Q2
Enhancemnet-:
Consider same case and use comamnd : mapred queue -showacls (with user U4 who
is not part of UG1 group).
It shows -:
[
Queue acls for user : U5
]
It would be better if we show some message e.g. (User does haves perssions on
any queue) instead of showing blank line
> Provide a way for users to find out what operations they can do on which M/R
> queues

> This issue is to provide an improvement on the existing M/R framework to let
> users know which queues they have access to, and for what operations. One use
> case for this would that currently there is no easy way to know if the user
> has access to submit jobs to a queue, until it fails with an access control
> exception.
