Siddharth Seth commented on MAPREDUCE-3903:
-------------------------------------------
Looked at the patch. Looks good. One minor nit - the debug log should be within
an if debug enabled check.
Not necessarily related to this patch - yarn has ACLs enabled by default, MR
has them disabled by default. That can lead to strange behavior considering
some of the calls like killJob use Yarn ACLs, while getJobStatus will use MR
ACLs. The Yarn ACLs could be disabled by default as well.
> no admin override to view jobs on mr app master and job history server

> in 1.0 there was a config mapreduce.cluster.administrators that allowed

> yarn has the new config yarn.admin.acl but it appears the mr app master and
