Hudson commented on YARN-2704:
------------------------------

SUCCESS: Integrated in Hadoop-Yarn-trunk #731 (See 
[https://builds.apache.org/job/Hadoop-Yarn-trunk/731/])
YARN-2790. Fixed a NodeManager bug that was causing log-aggregation to fail 
beyond HFDS delegation-token expiry even when RM is a proxy-user (YARN-2704).

> In secure mode, YARN requires the hdfs-delegation token to do localization 
> and log aggregation on behalf of the user. But the hdfs delegation token will 
> eventually expire after max-token-life-time.  So,  localization and log 
> aggregation will fail after the token expires.
