[YARN-3482] Report NM resource capacity in heartbeat

• Type: Improvement
• Status: Open
• Priority: Major
• Resolution: Unresolved

Description

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.
