Thomas Graves created YARN-180: ---------------------------------- Summary: Capacity scheduler - containers that get reserved create container token to early Key: YARN-180 URL: https://issues.apache.org/jira/browse/YARN-180 Project: Hadoop YARN Issue Type: Bug Components: capacityscheduler Affects Versions: 0.23.3 Reporter: Thomas Graves Priority: Critical
The capacity scheduler has the ability to 'reserve' containers. Unfortunately before it decides that it goes to reserved rather then assigned, the Container object is created which creates a container token that expires in roughly 10 minutes by default. This means that by the time the NM frees up enough space on that node for the container to move to assigned the container token will most likely have expired. -- This message is automatically generated by JIRA.
