> Issue Type: Bug
> Components: security
> Reporter: Jian He
>
> Opening on [~arpitgupta]'s behalf.
> We observed that, in HDFS HA mode, running Distcp/SLive with webhdfs will
> fail on YARN. In non-HA mode, it'll pass.
> The reason is in HA mode, only webhdfs delegation token is generated for the
> job, but YARN also requires the regular hdfs token to do localization,
> log-aggregation etc.
> In non-HA mode, both tokens are generated for the job.
