Zhijie Shen commented on YARN-572: ---------------------------------- There are three fields that are duplicate in Container and ContainerTokenIdentifier: 1. ContainerId 2. NodeId 3. Resource Though the fields are duplicated, it seems not good to remove them from Container. 1 and 2 are used to compare the Container objects and the getters of all the three are referred in multiple places tens of times. > Remove duplication of data in Container > ---------------------------------------- > > Key: YARN-572 > URL: https://issues.apache.org/jira/browse/YARN-572 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Hitesh Shah > Assignee: Zhijie Shen > > Most of the information needed to launch a container is duplicated in both > the Container class as well as in the ContainerToken object that the > Container object already contains. It would be good to remove this level of > duplication. -- This message is automatically generated by JIRA.
