MATLAB: Do I get an error when starting a worker from the Admin Center about “RECEIVE_F​AILED_INCO​MPATIBLE_V​ERSIONS”

MATLAB

When attempting to start a worker for MATLAB Parallel Server through the Admin Center, the worker start fails with the error:
com.mathworks.toolbox.distcomp.admincenter.testing.infra.util.TestFailureException: Test execution on 192.168.1.11:27352 failed. Cause: java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle, key RECEIVE_FAILED_INCOMPATIBLE_VERSIONS
What does this mean and how can I fix it?

  • This error will occur if you are using the Admin Center from a different release of MATLAB than what is on the MATLAB Parallel Server cluster. In order to start a worker, the Admin Center must be from the same release of MATLAB as you have on the cluster nodes.
    • NOTE: Starting in R2019a the following name changes occurred:
    • MATLAB Distributed Computing Server was renamed to MATLAB Parallel Server
    • mdce_def was renamed to mjs_def
    • mdce binary was renamed to mjs
