> When debugging the FSImage corruption issue, I often need to know a file's or
> directory's inode id. At this moment, the only way to do that is to use OIV
> tool to dump the FSImage and look up the filename, which is very inefficient.
> Here I propose adding option "-i" in FsShell that prints files' or
> directories' inode id.
> h2. Implementation
> h3. For hdfs:// (HDFS)
> fileId exists in HdfsLocatedFileStatus, which is already returned to
> hdfs-client. We just need to print it in Ls#processPath().
> h3. For file:// (Local FS)
> h4. Linux
> Use java.nio.
> h4. Windows
> Windows has the concept of "File ID" which is similar to inode id. It is
> unique in NTFS and ReFS.
> h3. For other FS
> The fileId entry will be "0" in FileStatus if it is not set. We could either
> ignore or throw an exception.
