SaintBacchus closed SPARK-10755.
--------------------------------
Resolution: Not A Problem
It's not a good idea to do so, since the hadoop rpc can automatically renew
the token by the keytab but it can't renew sucessfully.
This solution is not a root cause of this problem.
> Set the driver also update the token for long-running application

> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.6.0
> Reporter: SaintBacchus
>
> In the yarn-client mode, driver will write the event logs into hdfs and get
> the partition information from hdfs, so it's nessary to update the token from
> the *AMDelegationTokenRenewer*.
> In the yarn-cluster mode, driver is company with AM and token will update by
> AM. But it's still better to update the token for client process since the
> client wants to delete the staging dir with a expired token.
