Siyao Meng updated HDFS-16055:
------------------------------
Status: Patch Available (was: Open)
> 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
> Priority: Major
>
> 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}
