Varun Saxena created YARN-3986: ---------------------------------- Summary: getTransferredContainers in AbstractYarnScheduler should be present in YarnScheduler interface instead Key: YARN-3986 URL: https://issues.apache.org/jira/browse/YARN-3986 Project: Hadoop YARN Issue Type: Bug Components: scheduler Affects Versions: 2.7.0 Reporter: Varun Saxena Assignee: Varun Saxena
Currently getTransferredContainers is present in {{AbstractYarnScheduler}}. But in ApplicationMasterService, while registering AM, we are calling this method by typecasting it to AbstractYarnScheduler, which is incorrect. This method should be moved to YarnScheduler. Because if a custom scheduler is to be added, it will implement YarnScheduler, not AbstractYarnScheduler. As ApplicationMasterService is calling getTransferredContainers by typecasting it to AbstractYarnScheduler, it is imposing an indirect dependency on AbstractYarnScheduler for any pluggable custom scheduler. We can move the method to YarnScheduler and leave the definition in AbstractYarnScheduler as it is. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
