      Description

      It appears that NNs talk to JNs via general SaslRPC in secure mode, causing all requests to be carried out with a kerberos authentication. This can cause delays and occasionally NN failures if the KDC used does not respond in its default timeout period (30s, whereas the QJM writes come with default of 20s).
