Suma Shivaprasad created YARN-8675:
--------------------------------------
Summary: Setting hostname of docker container breaks with "host"
networking mode for Apps which do not run as a YARN service
Key: YARN-8675
URL: https://issues.apache.org/jira/browse/YARN-8675
Project: Hadoop YARN
Issue Type: Bug
Reporter: Suma Shivaprasad
Assignee: Suma Shivaprasad
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.
The proposal is to not set the hostname when "host" networking mode is enabled.
