示例1: getFileInfo

FSDirectory fsd, String src, boolean resolveLink, boolean isRawPath,
boolean includeStoragePolicy)

示例3: getFileInfo4DotSnapshot
/**
* Currently we only support "ls /xxx/.snapshot" which will return all the
* snapshots of a directory. The FSCommand Ls will first call getFileInfo to
* make sure the file/directory exists (before the real getListing call).
* Since we do not have a real INode for ".snapshot", we return an empty
* non-null HdfsFileStatus here.
