Inigo Goiri created YARN-3482:
---------------------------------
Summary: Report NM available resources in heartbeat
Key: YARN-3482
URL: https://issues.apache.org/jira/browse/YARN-3482
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager, resourcemanager
Affects Versions: 2.7.0
Reporter: Inigo Goiri
NMs are usually collocated with other processes like HDFS, Impala or HBase. To
manage this scenario correctly, YARN should be aware of the actual available
resources. The proposal is to have an interface to dynamically change the
available resources and report this to the RM in every heartbeat.
