Suma Shivaprasad updated YARN-8675: ----------------------------------- 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. was: 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.
