> 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: 5h 50m
> 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.
