      port number changes for resourcemanager and nodemanager
    • Tags:
      Yarn default ports nodemanager resourcemanager

      Description

      The default port numbers chosen for nodemanager and resourcemanager are random and widely spread out creating unnecessary overhead in deployments where site operators care, and deploy many clusters.

      Current and proposed new default ports are as follows:

      Current New Config Property
      ------- — ---------------
      4344 8040 yarn.nodemanager.localizer.address
      45454 8041 yarn.nodemanager.address
      9999 8042 yarn.nodemanager.webapp.address

      8030 8030(NC) yarn.resourcemanager.scheduler.address
      8025 8031 yarn.resourcemanager.resource-tracker.address
      8040 8032 yarn.resourcemanager.address
      8141 8033 yarn.resourcemanager.admin.address

      Affected files include: embedded defaults (YarnConfiguration.java), yarn-default.xml, documentation and unit tests.
