Date Tue, 03 Feb 2015 08:09:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-3094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14302924#comment-14302924

Rohith commented on YARN-3094:
------------------------------

patch looks overall good, 
nit : there is unused import in test class : org.apache.hadoop.yarn.util.Clock. This can be
removed

> When RM restarts, it will recover RMAppAttempts and registry them to AMLivenessMonitor
if they are not in final state. AM will time out in RM if the recover process takes long time
due to some reasons(e.g. too many apps). 
> In our system, we found the recover process took about 3 mins, and all AM time out.
