    Description

      Applications like the Spark AM currently do not run as a YARN service and setting hostname breaks driver/executor communication if docker version >=1.13.1 , especially with wire-encryption turned on.

      YARN-8027 sets the hostname if YARN DNS is enabled. But the cluster could have a mix of YARN service/native Applications.

      The proposal is to not set the hostname when "host" networking mode is enabled.
