Yahoo launched Haadop in production today and I have to say the statistics are bloody unbelievable. Whomever questioned Microsoft's reasons for wanting to buy this company may either be a financial analyst or partially crazy.
Statistics:
- Number of links between pages in the index: roughly 1 trillion links
- Size of output: over 300 TB, compressed!
- Number of cores used to run a single Map-Reduce job: over 10,000
- Raw disk used in the production cluster: over 5 Petabytes
