Time Spent: 3h (was: 2h 50m)
> Support nested mount points in INodeTree
> ----------------------------------------
>
> Key: HADOOP-18193
> URL: https://issues.apache.org/jira/browse/HADOOP-18193
> Project: Hadoop Common
> Issue Type: Improvement
> Components: viewfs
> Affects Versions: 2.10.0
> Reporter: Lei Yang
> Assignee: Lei Yang
> Priority: Major
> Labels: pull-request-available
> Attachments: Nested Mount Point in ViewFs.pdf
>
> Time Spent: 3h
> Remaining Estimate: 0h
>
> Defining following client mount table config is not supported in INodeTree and will throw FileAlreadyExistsException
>
> {code:java}
> fs.viewfs.mounttable.link./foo/bar=hdfs://nn1/foo/bar
> fs.viewfs.mounttable.link./foo=hdfs://nn02/foo
> {code}
> INodeTree has 2 methods that need change to support nested mount points.
> {code:java}
> createLink(): build INodeTree during fs init.
> resolve(): resolve path in INodeTree with viewfs apis.
> {code}
> ViewFileSystem and ViewFs maintains an INodeTree instance(fsState) in both classes and call fsState.resolve(..) to resolve path to specific mount point. INodeTree.resolve encapsulates the logic of nested mount point resolving. So no changes are expected in both classes.
> AC:
> # INodeTree.createlink should support creating nested mount points.(INodeTree is constructed during fs init)
> # INodeTree.resolve should support resolve path based on nested mount points. (INodeTree.resolve is used in viewfs apis)
> # No regression in existing ViewFileSystem and ViewFs apis.
> # Ensure some important apis are not broken with nested mount points. (Rename, getContentSummary, listStatus...)
>
> Spec:
> Please review attached pdf for spec about this feature.
