> Currently the ContainerStorageLocation#ContainerStorageLocation does not resolve to the
actual container prefix before passing it to CachingGetSpaceUsed for calculation. As a result
of that, if SCM datanode is running along with HDFS datanode, the HDFS datanode usage will
be included in scmUsage too, which is incorrect. This ticket is opened to fix it. 
> {code}
>     this.scmUsage = new CachingGetSpaceUsed.Builder().setPath(dataDir)
>         .setConf(conf)
>         .setInitialUsed(loadScmUsed())
>         .build();
> {code}
