Description

We use POLoad to seek into right file which has the following code:

   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);

    }

Between opening the stream and bindTo we do not seek to the right offset. bindTo itself does not perform any seek.
