-----------------------------------
Just found the follow fail. Does not seem to be repeatable by seed, must be
timing or something.

> Currently when we create a backup we use SimpleFSDirectory to write the
> backup indexes. Similarly during a restore we open the index using
> FSDirectory.open .
> We should provide a param called {{directoryImpl}} or {{type}} which will be
> used to specify the Directory implementation to backup the index.
> Likewise during a restore you would need to specify the directory impl which
> was used during backup so that the index can be opened correctly.
> This param will address the problem that currently if a user is running Solr
> on HDFS there is no way to use the backup/restore functionality as the
> directory is hardcoded.
> With this one could be running Solr on a local FS but backup the index on
> HDFS etc.
