> TestAMRMProxy#testE2ETokenRenewal fails sporadically due to race conditions

>                 Key: YARN-6813
>                 URL: https://issues.apache.org/jira/browse/YARN-6813
>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: test
>    Affects Versions: 2.8.1
>            Reporter: Jason Lowe
>            Priority: Major
>
> The testE2ETokenRenewal test lowers the AM and nodemanager heartbeat 
> intervals to only 1.5 seconds.  This leaves very little headroom over the 
> default heartbeat intervals of 1 second. If the AM hits a hiccup and runs a 
> bit slower than expected the unit test can fail because the RM expires the AM.
