>     Configuration allocConf = new Configuration(false);   <---- Doesn't load the default Hadoop configs
>     allocConf.set(FairSchedulerConfiguration.ALLOCATION_FILE, fsAllocationURL.getPath());
>     allocLoader_ = new AllocationFileLoaderService();
>     allocLoader_.init(allocConf);
> {noformat}
> The affect of this bug is that {{LDAPGroupsMapping}} cannot be used with fair scheduler's query -> resource pool mapping. It only loads the default {{ShellBasedUnixGroupsMapping}}
