> Found that search order for locations is following the order of these locations added to HFileLink object. 
>  
> setLocations(originPath, tempPath, mobPath, archivePath);
> archivePath is the last one to be searched. For most cases, hfile exists in archivePath, so we can move archivePath to the first parameter to avoid unnecessary NN query.
