Description

HADOOP-10211 made a backward incompatible change due to which the following hive call returns a null map (HiveAuthFactory-old):

Map<String, String> hadoopSaslProps =  ShimLoader.getHadoopThriftAuthBridge().
        getHadoopSaslProperties(conf); 
SaslQOP hadoopSaslQOP = SaslQOP.fromString(hadoopSaslProps.get(Sasl.QOP));
if(hadoopSaslQOP.ordinal() > saslQOP.ordinal()) {
LOG.warn(MessageFormat.format("\"hadoop.rpc.protection\" is set to higher security level " +
          "{0} then {1} which is set to {2}", hadoopSaslQOP.toString(),
          ConfVars.HIVE_SERVER2_THRIFT_SASL_QOP.varname, saslQOP.toString()));
}

Since this code path is only used for logging hadoop sasl qop values in case hadoop's qop > hive's qop, we can do away with this and add a general log message.
