Karthik Kambatla commented on YARN-3482: ---------------------------------------- For the third config, would something like yarn.nodemanager.dynamic-resource-availability=true/false be more descriptive? Admin interface (with a special command) sounds reasonable. > 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 > Original Estimate: 504h > Remaining Estimate: 504h > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
