Jian He commented on YARN-2704:
-------------------------------
bq. this is really a YARN responsibility and so it should automatically get
tokens that are needed
Agree, we should let YARN automatically request new hdfs token on behalf of the
user for localization and log-aggregation. I'm creating a patch based on this
idea.
> 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.
