Pre Hadoop Summit meetup: Andrew Wang, Chris Wensel and Doug Cutting

The Hadoop Summit will be in Amsterdam again on April 2-3, 2014. There will be a NL-HUG meetup on the night before (yes, that would be April 1st). This is placeholder announcement to mark the date. Further information will follow when we finalize the agenda. 


17.30: arrive, socialize, eat, drink

19.00: Presentations

In-memory Computation and HDFS: What's Next?, Andrew Wang, Hadoop Committer

With increasing per-node RAM capacity, in-memory computation is becoming more and more attractive. Newer computational frameworks like Apache Spark are even explicitly designed to take advantage of this in-memory paradigm. However, where does this leave HDFS, which has was originally designed for spinning disks? In this talk, I'll discuss a number of recent changes in HDFS that help to address this gap, and extrapolate to future roadmap items that would further improve integration with frameworks like Spark.

A Quick Introduction to the Cascading Ecosystem, Chris Wensel, creator of Cascading

Cascading is an application development platform for building data applications on Hadoop. And the foundation for projects like Scalding, Lingual, and Cascalog.

Balancing Data Collection and Privacy, Doug Cutting, creator of Hadoop

Data has great potential to improve the world.  For example, societies benefit from healthy, educated citizens.  Healthcare and education improve when new patterns are discovered.  However some valuable patterns are only discoverable through collection of personal data. Complete anonymization is impossible in many cases.  Thus to obtain benefits, we must collect personalized data.  Yet we must also avoid becoming a surveillance society, with reduced privacy.  I will suggest some ideas for how we can both obtain the benefits of data collection without discarding our privacy.

20.30 - later: Drinks and socialize more

    Hi, are you working with personal user data(like social media) ?
    I would like some tips how to don't scare the users and how to prove them that I only want to help them.
    I know that Doug Cutting will speak about it, but I would also like to hear some tips from you, maybe some realtime use cases.

    Hi there, Are there any people attending this meetup that are also using technologies like Presto and/or Cassandra in combination with Hadoop and Map/Reduce? Maybe interesting to have a quick chat on these topics during the drinks at the end of the evening.

    • Tim M.

      Hi Robin, I can talk about this from a vendor perspective at least. I'll be arriving later in the evening (probably around 9).

      Hi Robin

      We are using Cassandra as our main database for a project in which we also want run Mapreduce Jobs. Our experience is only at theoretical level, but it could be great to share ideas about integration Cassandra and Hadoop.

    Last year's event were amazing, looking forward for this one. Btw, do you know how can I find a discount voucher for hadoop summit?

    February 4, 2014

    • Friso van V.

      Hi Rahim, I'm not aware of any discount codes, other than early bird and group discounts (25% for groups of 4 or multiples thereof). You could inquire at the summit organization for student prices, but there's nothing published on their website about this. Good luck! Friso

    • Friso van V.

      Hmm... It seems I actually forgot about a membership perk offered to members of this group by Hortonworks. You get at least a 10% discount using the membership perk (somewhere on the group homepage).
