Santosh Marella commented on YARN-1108:
---------------------------------------
Hey guys.. I noticed that client-to-AM tokens are issued only when security is
enabled, unlike other tokens (for e.g. AM to RM), and stumbled on this JIRA
when trying to find out why.
Looks like not much activity on this, but, just curious if there was any reason
why client-to-AM tokens are issued only when security is enabled.
> Always use tokens for client-to-AM connections

> Key: YARN-1108
> URL: https://issues.apache.org/jira/browse/YARN-1108
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.1.0-beta
> Reporter: Jason Darrell Lowe
> Priority: Major
>
> Most of the tokens in YARN are used regardless of whether security is
> enabled. The client-to-AM token is an exception, and it would be nice if
> this were treated like the others. This would consolidate code paths for
> easier testing.
