Run a secondary mapreduce job accepting as input, the output of the first action. The values to write in the Mapper could be (NullWritable, line), as you want to collect all lines to a single reducer, but you don't really care about a key otherwise, then parse out the number of each line, keeping track of the current maximum value and its associated line. After looping over all values, write the maximum line.

To improve the run time of this process, use setCombinerClass in your job configuration to use this new reducer

Scrolled element should be position: relative style.

Edit

Your divs height are too small. Scroll area is to short for scroll-spy.

Edit2

As @Lars mentioned the problem was a typo: style="heigt: 100%" instead of style="height: 100%" in body element.
