> Project: Hadoop Map/Reduce
> Issue Type: Bug

>
>
> By default, the service field of a delegation token is populated based on
> server IP address. Setting {{hadoop.security.token.service.use_ip}} to
> {{false}} changes this behavior to use host name instead of IP address.
> However, this configuration property is not read from job.xml. Instead, it's
> read from a separate {{Configuration}} instance created during static
> initialization of {{SecurityUtil}}. This does not work correctly with
> MapReduce jobs if the framework is distributed by setting
> {{mapreduce.application.framework.path}} and the
> {{mapreduce.application.classpath}} is isolated to avoid reading
> core-site.xml from the cluster nodes. MapReduce tasks will fail to
> authenticate to HDFS, because they'll try to find a delegation token based on
> the NameNode IP address, even though at job submission time the tokens were
> generated using the host name.
