---------------------------------

             Summary: Quota is not preserved in snapshot INode
                 Key: HDFS-16055
                 URL: https://issues.apache.org/jira/browse/HDFS-16055
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
    Affects Versions: 3.3.0
            Reporter: Siyao Meng
            Assignee: Siyao Meng


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}
