Siyao Meng created HDFS-16055:
---------------------------------
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}
