Doing More with the Hortonworks Sandbox by Cheryle Custer.
From the post:
The Hortonworks Sandbox was recently introduced garnering incredibly positive response and feedback. We are as excited as you, and gratified that our goal providing the fastest onramp to Apache Hadoop has come to fruition. By providing a free, integrated learning environment along with a personal Hadoop environment, we are helping you gain those big data skills faster. Because of your feedback and demand for new tutorials, we are accelerating the release schedule for upcoming tutorials. We will continue to announce new tutorials via the Hortonworks blog, opt-in email and Twitter (@hortonworks).
While you wait for more tutorials, Cheryle points to some data sets to keep you busy:
- Public Data available on Google
- Open Data Initiative from the US Government
- Microsoft Bing Spatial Data Services
- US Government XML Data sources
- Free downloadable datasets from InfoChimps
For advice, see the Sandbox Forums.
BTW, while you are munging across different data sets, be sure to notice any semantic impedance if you try to merge some data sets.
If you don’t want everyone in your office doing that merging one-off, you might want to consider topic maps.
Design and document a merge between data sets once, run many times.
Even if your merging requirements change. Just change that part of the map, don’t re-create the entire map.
What if mapping companies recreated their maps for every new street?
Or would it be better to add the new street to an existing map?
If that looks obvious, try the extra-bonus question:
Which model, new map or add new street, do you use for schema migration?
