Lavkesh Lahngir created YARN-3933: ------------------------------------- Summary: Resources(bothe core and memory) are being negative Key: YARN-3933 URL: https://issues.apache.org/jira/browse/YARN-3933 Project: Hadoop YARN Issue Type: Bug Reporter: Lavkesh Lahngir Assignee: Lavkesh Lahngir
In our cluster we are seeing available memory and cores being negative. Initial inspection: Scenario no. 1: In capacity scheduler the method allocateContainersToNode() checks if there are excess reservation of containers for an application, and they are no longer needed then it calls queue.completedContainer() which causes resources being negative. And they were never assigned in the first place. I am still looking through the code. Can somebody suggest how to simulate excess containers assignments ? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
