> Quota feature is not preserved during snapshot creation, this causes 
> {{INodeDirectory#metadataEquals}} to ALWAYS return true. Therefore, 
> {{snapshotDiff}} will ALWAYS return the snapshot root as modified, even if 
> the quota is set before the snapshot creation:
> {code:bash}
> $ hdfs snapshotDiff /diffTest s0 .
> Difference between snapshot s0 and current directory under directory 
> /diffTest:
> M     .
> {code}
