-------------------------------------------
Summary: Implement getLinkTarget for ViewFileSystem
Key: HADOOP-13885
URL: https://issues.apache.org/jira/browse/HADOOP-13885
Project: Hadoop Common
Issue Type: Task
Components: viewfs
Affects Versions: 3.0.0-alpha1
Reporter: Manoj Govindassamy
Assignee: Manoj Govindassamy
ViewFileSystem doesn't override FileSystem#getLinkTarget(). So, when view
filesystem is used to resolve the symbolic links, the default FileSystem
implementation throws UnsupportedOperationException.
The proposal is to define getLinkTarget() for ViewFileSystem and invoke the
target FileSystem for resolving the symbolic links. Path thus returned is
preferred to be a viewfs qualified path, so that it can be used again on the
ViewFileSystem handle.
