Eric Yang updated YARN-7323:
----------------------------
Description:
Unix terminology implies daemon process, such as httpd as a service. In Hadoop
terminology, hdfs is a file system service, and hdfs has various components
such as namenode, journal nodes, and datanodes. YARN service data model was
more closely describing daemon process as a service. This JIRA propose to
remap the YARN service data model to align with Hadoop terminology. Service is
composed of a collection of components. Component is either a unix process or
docker container.
Data structure for Yarnfile organized launched_command and state at Service
level, but the grouping definition was following Hadoop terminology. For
clarity, we will change data structure to match Hadoop terminology. State and
launch commands are moved to component level.
was:Data structure for Yarnfile organized state at service level.
