Description

truncate will fail when use viewFS.

  @Override
  public boolean truncate(final Path f, final long newLength)
      throws IOException {
    InodeTree.ResolveResult<FileSystem> res =
        fsState.resolve(getUriPath(f), true);
    return res.targetFileSystem.truncate(f, newLength);
  }
  

Path should be like below:
return res.targetFileSystem.truncate(f, newLength); should be return res.targetFileSystem.truncate(res.remainingPath, newLength);
