Andrew Wang commented on HDFS-10918:
------------------------------------
I think we still are missing handling relative paths and symlinks. Let's look
at getFileStatus:
{code}
public FileStatus getFileStatus(Path f) throws IOException {
Path absF = fixRelativePart(f); // <----------- uses the CWD to turn
relative into absolute paths
return new FileSystemLinkResolver<FileStatus>() { // <------- class to keep
following symlinks until path is fully resolved
@Override
public FileStatus doCall(final Path p) throws IOException {
HdfsFileStatus fi = dfs.getFileInfo(getPathName(p));
if (fi != null) {
return fi.makeQualified(getUri(), p);
} else {
throw new FileNotFoundException("File does not exist: " + p);
}
}
@Override
public FileStatus next(final FileSystem fs, final Path p)
throws IOException {
return fs.getFileStatus(p);
}
}.resolve(this, absF);
}
{code}
Looking at this more closely myself, code sharing is pretty tough because we
need that HdfsFileStatus which is only returned by an HDFS. There are other
examples of ops that can only resolve symlinks through a DFS instance, e.g.
{{renameSnapshot}}, that you can use as an example.
