Gopal V created YARN-2422:
-----------------------------
Summary: yarn.scheduler.maximum-allocation-mb should not be
hard-coded in yarn-default.xml
Key: YARN-2422
URL: https://issues.apache.org/jira/browse/YARN-2422
Project: Hadoop YARN
Issue Type: Bug
Components: scheduler
Affects Versions: 2.6.0
Reporter: Gopal V
Priority: Minor
Attachments: YARN-2422.1.patch
Cluster with 40Gb NM refuses to run containers >8Gb.
It was finally tracked down to yarn-default.xml hard-coding it to 8Gb.
In case of lack of a better override, it should default to -
${yarn.nodemanager.resource.memory-mb} instead of a hard-coded 8Gb.
