Jian He commented on YARN-2704:
-------------------------------
bq. if (this.token==null || this.applicationId==null || this.conf==null) {“
because this null checks can not happen, and was causing previous find bugs
warning.
> Localization and log-aggregation will fail if hdfs delegation token expired
> after token-max-life-time

> 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.
