Hi ALL,

Can  Anyone tell me when following finalize option will be used.<= /div>

 case FINALIZE: {         boolean aborted =3D finali= ze(conf, true); 
        System.exit(aborted ? 1 : 0); 
        return null; // avoid javac warning 




 private static = ;boolean<= /b> finalize(Configuratio= n conf, 
          &n= bsp;                    <= /font>boolean isConfirmationNeeded&nb= sp;
          &n= bsp;                    )=  thr= ows IOException {&nbs= p;
    String nsId =3D DFSUtil= .getNamenodeNameServiceId(conf); 
    String namenodeId =3D H= AUtil.getNameNodeId(conf, nsId); 
    initializeGener= icKeys(conf, nsId, namenodeId); 

    FSNamesystem nsys =3D&n= bsp;new FSNamesystem(conf,&nbs= p;new=  FSImage(conf)); 
    System.err.print( 
        "\"fin= alize\" will remove the previous state of the files system.\n"&nb= sp;
        +&nbs= p;"Rece= nt upgrade will become permanent.\n" 
        +&nbs= p;"Roll= back option will not be available anymore.\n"); 
    if (isConfirmationNeeded) { 
      if (!confirmPrompt("Finalize filesystem s= tate?")) {         System.err.println("Finalize aborted."<= font size=3D"2" face=3D"Courier New">); 
        return true; 
      }      } 
    nsys.dir.fsImage.finalizeUpgrad= e(); 
    return false; 
  } 
      
I thought after up-gradatio= n it'll be used to finalize filesystem instead of finalize upgrad= e. But it was failing by logging following in .out log and it process got h= ang since it's expecting input which we can't give.
