Arun Suresh commented on YARN-4412:
-----------------------------------
[~aw], I apologize..
But I did mentioned
[here|https://issues.apache.org/jira/browse/YARN-4412?focusedCommentId=15148978&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15148978]
that the call to {{System.exit(-1)}} is actually intentional (the dispatch
MUST bring down the process if it hits a fatal error).. and was flagged as a
consequence of (plain-vanilla IDE assisted) refactoring of an existing inner
class into a new class, which means its a findbugs that already existed.
The patch process detects increase in findbugs due to a patch, but does not
record a decrease, which is the case with this patch..
Maybe there is a better alternative to using System.exit() ? But dont you feel
that should be explored outside of this JIRA ?

> Introduce a Cluster Monitor that aggregates load information from individual
> Node Managers and computes an ordered list of preferred Node managers to be
> used as target Nodes for OPPORTUNISTIC container allocations.
> This list can be pushed out to the Node Manager (specifically the AMRMProxy
> running on the Node) via the Allocate Response. This will be used to make
> local Scheduling decisions
