> In a secure environment, when both HDFS HA and log aggregation are turned on,
> {{JavaActionExecutor}} is not able to call {{YarnClient#submitApplication}}
> since {{HDFS_DELEGATION_TOKEN}} is missing.
> In those cases we need to get {{HDFS_DELEGATION_TOKEN}} from YARN:
> * get server principal / YARN renewer via
> {{HadoopAccessorService#getServerPrincipal}}
> * get {{HDFS_DELEGATION_TOKEN}} via {{DFSClient#getDelegationToken}}
> * add {{HDFS_DELEGATION_TOKEN}} to {{Credentials}}
