Vinod K V commented on MAPREDUCE-1604:
--------------------------------------

I agree with your comments about documentation being part of the whole.

My only problem here is Job-acls ARE an unstable feature. The moment one 
configures job-acls to be used, issues like MAPREDUCE-1664 crop up. Also if 
MAPREDUCE-1664 doesn't go in 0.21, we will need to support 
_job-authorization.enabled_ flag in 0.22 as it is going away in favour of 
mapred-acls-enabled flag.

I am just trying to see if we should remove the documentation of this feature 
for release 0.21 and get the complete feature in for 0.22. I am not sure of any 
process via which we can tell users about known issues. Even if we have one, 
I'd rather prefer turning off this feature completely in 0.21 as without 
MAPREDUCE-1664 and related issues, this issue is practically useless. What do 
you think about it?
