Summary: Unchecked typecast to AbstractYarnScheduler in AppInfo Key: YARN-4078 URL: https://issues.apache.org/jira/browse/YARN-4078 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Reporter: Naganarasimha G R Assignee: Naganarasimha G R Priority: Minor Currently getPendingResourceRequestForAttempt is present in {{AbstractYarnScheduler}}. *But in AppInfo, we are calling this method by typecasting it to AbstractYarnScheduler, which is incorrect.* Because if a custom scheduler is to be added, it will implement YarnScheduler, not AbstractYarnScheduler. This method should be moved to YarnScheduler or it should have a guarded check like in other places (RMAppAttemptBlock.getBlackListedNodes) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
