> The SentryPolicyStoreProcessor needs to get the groupMappingService to parse username. The function code as followings:
> {code}
>     String groupMapping = conf.get(ServerConfig.SENTRY_STORE_GROUP_MAPPING,
>         ServerConfig.SENTRY_STORE_GROUP_MAPPING_DEFAULT);
>     String authResoruce = conf
>         .get(ServerConfig.SENTRY_STORE_GROUP_MAPPING_RESOURCE);
>     Constructor<?> constrctor = Class.forName(groupMapping)
>           .getDeclaredConstructor(Configuration.class, String.class);
>       constrctor.setAccessible(true);
>       groupMappingService = (GroupMappingService) constrctor
>           .newInstance(new Object[] { conf, authResoruce });
> {code}
> When create a HadoopGroupMappingService new instance, it will throw a NoSuchMethodException, the log is as following:
