I wanted to blog about some impressions and personal notes that I made during the EU Hadoopsummit. First impression: it was a huge grab-bag and lots of fun. Vendors and presentations were all tuned to YARN (Hadoop 2.0) already. Clear message here: if you are new to Hadoop, do not keep yourself busy with Hadoop 1.0 anymore.
On the vendor side it seems that many vendors that are doing something with data (analytics) want to get somehow access to the Hadoop Ecosystem. Probably just in case the brave predictions that Hadoop is going to overtake RDBMs become true. Vendors want to be prepared for the day when Hadoop is going to rule. –They do not seem too disappointed however if this is never going to happen.
On the security side you have one or two vendors that have some compelling story, some of these I will address in my talks at the Gartner EU catalyst and in an upcoming research note about Hadoop security.
The Hadoop “ecosystem” is still quite scary to many. I attended some sessions where the audience just did not understand where a certain component or feature would fit into the Hadoop Ecosystem; interestingly some of the speakers did not know this either. Really. But, given the size and many moving parts of the Hadoop Ecosystem, I think this is all right.
During the breaks, many interesting discussions about the nature of data, data being a new asset class (and the electricity cost coming on top of it) or data being the new oil. I do love the term “Data Dwellers”.
What I did miss was some reality checks. In the sessions developers were so excited about the progress they make that frequently they did not hesitate to recommend features that were committed two weeks ago for operational deployment and use. One speaker added that probably a rolling deployment was the most sensible. In short, I missed all these real-life stories, these drifts, bugs and issues you always get in large scale technology projects. Apart from that: well done.
