>  [HADOOP-10211|https://issues.apache.org/jira/browse/HADOOP-10211] made a backward incompatible
change due to which the following hive call returns a null map ([HiveAuthFactory-old|https://github.com/apache/hive/blob/fc3fdb19668369c56994d11df3207e14f2c5dba8/service/src/java/org/apache/hive/service/auth/HiveAuthFactory.java#L115]):

> 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

>           ConfVars.HIVE_SERVER2_THRIFT_SASL_QOP.varname, saslQOP.toString()));
> }
> {code}
> 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.
