-----------------------------
Summary: Container allocation issue in Leafqueue assignContainers()
Key: YARN-1631
URL: https://issues.apache.org/jira/browse/YARN-1631
Project: Hadoop YARN
Issue Type: Bug
Components: scheduler
Affects Versions: 2.2.0
Environment: SuSe 11 Linux
Reporter: Sunil G
Application1 has a demand of 8GB[Map Task Size as 8GB] which is more than
Node_1 can handle.
Node_1 has a size of 8GB and 2GB is used by Application1's AM.
Hence reservation happened for remaining 6GB in Node_1 by Application1.
A new job is submitted with 2GB AM size and 2GB task size with only 2 Maps to
run.
Node_2 also has 8GB capability.
But Application2's AM cannot be launched in Node_2. And Application2 waits
longer as only 2 Nodes are available in cluster.
