Summary: On AM registration, response should include cluster Nodes report on demanded by registration request. Key: YARN-4278 URL: https://issues.apache.org/jira/browse/YARN-4278 Project: Hadoop YARN Issue Type: Improvement Components: api Reporter: Rohith Sharma K S Assignee: Rohith Sharma K S >From the yarn-dev mailing list discussion thread >[Thread-1|http://mail-archives.apache.org/mod_mbox/hadoop-yarn-dev/201510.mbox/%3c0ee80f6f7a98a64ebd18f2be839c91156798a...@szxeml512-mbs.china.huawei.com%3E] > >[Thread-2|http://mail-archives.apache.org/mod_mbox/hadoop-yarn-dev/201510.mbox/%3c4f7812fc-ab5d-465d-ac89-824735698...@hortonworks.com%3E] > Slider required to know about cluster nodes details for providing support for affinity/anti-affinity on containers. Current behavior : During life span of application , updatedNodes are sent in allocate request only if there are any change like added/removed/'state change' in the nodes. Otherwise cluster nodes not updated to AM. One of the approach thought by [~ste...@apache.org] is while AM registration let response hold the cluster nodes report -- This message was sent by Atlassian JIRA (v6.3.4#6332)
