> We use POLoad to seek into right file which has the following code: 
> {noformat}
>    public void setUp() throws IOException{
>         String filename = lFile.getFileName();
>         loader = (LoadFunc)PigContext.instantiateFuncFromSpec(lFile.getFuncSpec()); 
      
>         is = FileLocalizer.open(filename, pc);
>         loader.bindTo(filename , new BufferedPositionedInputStream(is), this.offset,
Long.MAX_VALUE);
>     }
> {noformat}
> Between opening the stream and bindTo we do not seek to the right offset. bindTo itself
does not perform any seek.
