Connectivity issues to Yarn



  • Gido

    A common cause for this is the specific service isn't running on that port or that machine. This might be caused by (incorrect) Configuration of High Availability.

    Hello Nikhil,

    In addition to Gido's recommendation, I'd suggest to double check the following:

    • Ensure that RM host is up and running and you network connection is up as well. Most likely successful ping request will confirm this.

    • Ensure that Yarn service is running at target host on mentioned port.

    • Try to check connectivity to port 8032 via telnet
      e.g. telnet 8032

    • if you use Yarn High Availability, ensure that it ha been setup properly.
