Dear HUG UK members,

I am pleased to announce our November Meetup. This Meetup is being sponsored by Cloudera who are providing the venue and refreshments and flying two speakers over to the UK before the Strata + Hadoop World event in Barcelona. Thanks!

If you want to do a short five minute talk about your real world Hadoop setup then please get in touch with the team through [masked]

Note: The time has been changed to make it half an hour earlier - in line with most past meetups.

Alex McLintock
co-organiser of HUGUK

Time: Monday November 17th - Doors open 6:30pm,
Refreshments from 6:30pm to 7:00pm.
Presentations from 7:00pm to 9:00pm.
Location: Offices of Ketchum, 35-41 Folgate St, London, E1 6BX.

Session 1: Architectural considerations for Hadoop applications
Speaker: Mark Grover, Software Engineer, Cloudera
Speaker: Ted Malaska, Sr Solution Architect, Cloudera

In this talk we’ll walk through an end-to-end case study of a clickstream analytics engine to provide a concrete example of how to architect and implement a complete solution with Hadoop. We’ll use this example to illustrate important topics such as:
• Modeling data in Hadoop and selecting optimal storage formats for data stored in Hadoop
• Moving data between Hadoop and external data management systems such as relational databases
• Moving event-based data such as logs and machine generated data into Hadoop
• Accessing and processing data in Hadoop
• Orchestrating and scheduling workflows on Hadoop
Throughout the example, best practices and considerations for architecting applications on Hadoop will be covered. This talk will be valuable for developers, architects, or project leads who are already knowledgeable about Hadoop, and are now looking for more insight into how it can be leveraged to implement real-world applications.

Session 2: Clickstream & Social Media Analysis with Apache Spark
Speaker: Michael Cutler, CTO of TUMRA

One of the most common use-cases for ‘Big Data’ tools is analysing Clickstream and Social Media data. The conventional way to achieve this involved using Hadoop Map/Reduce jobs to ‘extract, transform, and load’ (ETL) the raw data into a useful form which Analysts can use answer questions e.g. Hive tables. These ETL jobs were generally slow batch processes (introducing latency) and required Java developers to maintain and make any changes to the data schema.

Enter Apache Spark, a data processing engine designed for both batch and streaming workloads. The entire process of transforming the raw input data through to asking questions using a SQL-like interface can be achieved in one step, and it’s up to 100x faster than Map/Reduce & Hive. Did I forget to mention that it also has an interactive shell, machine learning and graph analysis baked in?

This talk will introduce Apache Spark and some of the use-cases we’ve successfully deployed with it, and will then dive into real example clickstream & social media analysis tasks illustrating how they can be achieved simply and quickly using Spark.
