Jason Lowe created TEZ-3535: ------------------------------- Summary: YarnTaskScheduler can hold onto low priority containers until they expire Key: TEZ-3535 URL: https://issues.apache.org/jira/browse/TEZ-3535 Project: Apache Tez Issue Type: Bug Affects Versions: 0.8.4, 0.7.1 Reporter: Jason Lowe Assignee: Jason Lowe
With container reuse enabled, YarnTaskScheduler will retain but not schedule any container allocations that are lower priority than the highest priority task requests. This can lead to poor performance as these lower priority containers clog up resources needed for high priority allocations. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
