Description

For more flexible configuration of HA, the SPN for NN's internal SPNEGO needs to be per-nn. Currently the config should contain "_HOST" or configured differently per node.

This change should not change the existing behavior unless the SPN is explicitly specified per NN under the HA configuration.
