Jian He updated YARN-2704:

bq. It’s inside the run method, so I wrap it with runTimeException
Ignore this comment, I changed to use PrivilegedExceptionAction whose run method declares
exception.

> 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.
