DN registration should use DataNodeLayoutVersion instead of NameNodeLayoutVersion

    Details

      Description

      Currently the registrationID is in the form of BlockPoolID-NNLayoutVersion. When the NN bumps the layout version during rolling upgrade, the DNs will fail to register with the new NN and exit, regardless whether the new software version is used.
