-----------------------------------------
Summary: INode#getSnapshotINode() should get INodeAttributes from
INodeAttributesProvider for the current INode
Key: HDFS-12201
URL: https://issues.apache.org/jira/browse/HDFS-12201
Project: Hadoop HDFS
Issue Type: Bug
Components: snapshots
Affects Versions: 2.8.0
Reporter: Manoj Govindassamy
Assignee: Manoj Govindassamy
{{INodeFile}}

@Override
public INodeFileAttributes getSnapshotINode(final int snapshotId) {
FileWithSnapshotFeature sf = this.getFileWithSnapshotFeature();
if (sf != null) {
return sf.getDiffs().getSnapshotINode(snapshotId, this);
} else {
return this;
}
}

{{AbstractINodeDiffList#getSnapshotINode}}
{noformat}
public A getSnapshotINode(final int snapshotId, final A currentINode) {
final D diff = getDiffById(snapshotId);
final A inode = diff == null? null: diff.getSnapshotINode();
return inode == null? currentINode: inode;
}
{noformat}
INodeFile, INodeDirectory #getSnapshotINode() returns the current INode's local
INodeAttributes if there is anything available for the given snapshot id. When
there is an INodeAttributesProvider configured, attributes are retrieved from
this external provider instead of the local. But, getSnapshotINode always
returns the local attributes without retrieving them from attributes provider.
