> When meta server znode deleted and meta in FAILED_OPEN state, then hbck cannot fix it.
This scenario can come when all region servers stopped by stop command and didnt start any
RS within 10 secs(with default configurations). 
> {code}
>   public void assignMeta() throws KeeperException {
>     MetaRegionTracker.deleteMetaLocation(this.watcher);
>     assign(HRegionInfo.FIRST_META_REGIONINFO, true);
>   }
> {code}
