Recap: <strong>Graph</strong> Algorithms <br />
• Many graph algorithms need iteraFve computaFon <br />
• No naFve support for iteraFon in Map-‐Reduce <br />
– Each iteraFon writes/reads data from disk leading to overheads <br />
– Need to design algorithms that can minimize number of iteraFons <br />
