[jira] [Updated] (YARN-4260) Check NodeManager's validity based on hostname(IP) and port

["jaehoon ko (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-4260?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

jaehoon ko updated YARN-4260:
-----------------------------
    Attachment: YARN-4260.001.patch

NodesListManager.isValidNode() now takes additional argument: int port.
This port corresponds to the port specified in yarn.nodemanager.address.
Hostname-only validity checking is still possible in case include/exclude file (specified in yarn.resourcemanager.nodes.include-path and yarn.resourcemanager.nodes.exclude-path) does not have port specified.

> There can be situations where multiple NMs are running on the same host; emulating multi-host YARN cluster on one host, deploying dockerized NMs that share network stack. In such cases, RM should be able to distinguish NMs running on the same host. However, current implementation checks validity of NM based only on hostname (NodesListManager.isValidNode()). So it is not possible to distinguish a specific NM from other NMs on the same host.
