> HADOOP-7284 added a test called TestViewFsTrash which contains the following
> code to determine the user's home directory. It only works if the user's
> directory is one level deep, and breaks if the home directory is more than
> one level deep (eg user hudson, who's home dir might be /usr/lib/hudson
> instead of /home/hudson).
> {code}
> // create a link for home directory so that trash path works
> // set up viewfs's home dir root to point to home dir root on target
> // But home dir is different on linux, mac etc.
> // Figure it out by calling home dir on target
>
> String homeDir = fsTarget.getHomeDirectory().toUri().getPath();
> int indexOf2ndSlash = homeDir.indexOf('/', 1);
> String homeDirRoot = homeDir.substring(0, indexOf2ndSlash);
> ConfigUtil.addLink(conf, homeDirRoot,
> fsTarget.makeQualified(new Path(homeDirRoot)).toUri());
> ConfigUtil.setHomeDirConf(conf, homeDirRoot);
> Log.info("Home dir base " + homeDirRoot);
> {code}
> Seems like we should instead search from the end of the path for the last
> slash and use that as the base, ie ask the home directory for its parent.
