Location: Bronto Software in Durham, NC
Abstract: Chris will provide an introduction to Apache HBase, aiming to discuss:
Bio: Chris Shain is the software development lead at Tresata, a provider of Big Data solutions for the financial industry in Charlotte NC. His background includes 7+ years of software development experience in the financial services industry, with a focus on customer-facing data management applications and data warehousing. Lately he works with Hadoop and HBase on data volumes in the multi-terabyte range, and tinkers with geographic information systems. He lives in Charlotte NC, and can be reached at chris@tresata.com or twitter @ChrisShain.
Thanks to Alan Gates of Hortonworks for the two excellent presentations on Apache Pig and Apache HCatalog. Links to the slides for the two talks are included below and are also available on Slideshare.

Title: New Features in Pig 0.9 and Introducing HCatalog
Abstract: Pig 0.9 added several features to make Pig a more powerful data processing platform, including macros, include statements, and the ability to embed Pig in Python for control flow. We’ll cover these, talk about some new features that have been added since 0.9, and what’s next on Pig’s roadmap.
HCatalog is a table management and storage management layer for Hadoop that enables users with different data processing tools – Pig, MapReduce, Hive, Streaming – to more easily read and write data on the grid. HCatalog’s table abstraction presents users with a relational view of data in the Hadoop distributed file system (HDFS) and ensures that users need not worry about where or in what format their data is stored – RCFile format, text files, sequence files. This talk will include an overview of HCatalog’s features and a discussion of its current roadmap.
Bio: Alan is a co-founder of Hortonworks as well as an original member of the engineering team that took Pig from a Yahoo! Labs research project to a successful Apache open source project. Alan also designed HCatalog and guided its adoption as an Apache Incubator project. Alan has a BS in Mathematics from Oregon State University and a MA in Theology from Fuller Theological Seminary. He is also the author of Programming Pig, a forthcoming book from O’Reilly Press. Follow Alan on Twitter: @alanfgates.
The next Triangle Hadoop User Group meeting will be October 11th at Bronto Software and will be featuring Josh Patterson of Cloudera. RSVP here.
Title: Lumberyard: Time series Indexing at Scale Abstract: As time series data explodes in volume in the genomic, sensor, and financial realms [1] companies are looking for more effective ways to store and query this data. To handle this explosion in scale systems are looking to the Hadoop, HBase, and NoSQL domain for components to build their systems on. In this talk we introduce Lumberyard [3], a system which can potentially (1) store Terabytes of time series data and allow for this data to be interactively queried at low latencies to provide real time access. Lumberyard stores iSAX [4] indexes in HBase’s Multi-dimensional sorted map storage system which give Lumberyard the reliability of HDFS yet the low latencies of HBase. Our approach leverages a multidimensional indexing structure which is stored in HBase’s highly available distributed multi-dimensional sorted map. We present the design of Lumberyard’s implementation and illustrate the differences between an in-memory iSAX index compared with a persisted HBase-backed iSAX index.

Under the better late than never category, here are the slides from the April 2011 TriHUG meeting on Starfish.

We trust everyone has had a good summer and is equally excited to get back into learning more about Apache Hadoop and scaling. Our next meeting will be Sept. 13 at Bronto Software. Food and drinks start at 6:30 and the talks start at 7.
We are pleased to announce that our speaker will be Ted Dunning from MapR Technologies. See below for more details. Please RSVP here.
Title: MapR, Architecture and Implications
Abstract:
The talk will be a description of how MapR’s architectural advances allow significant improvements in speed, reliability and scalability over stock Hadoop. This will include a dive into the MapR file system and a discussion of how the map-reduce layer has been changed and the impact on other Hadoop eco-system components. This will include actual test results.
In the second section of my talk, I will describe how this new architecture has surprising consequences. In particular, I will show how tasks like machine learning, data visualization and search indexing can all work better on the MapR platform.
Ted’s Bio:
Ted has held Chief Scientist positions at Veoh Networks, ID Analytics and at MusicMatch, (now Yahoo Music). Ted is responsible for building the most advanced identity theft detection system on the planet, as well as one of the largest peer-assisted video distribution systems and ground-breaking music and video recommendations systems. Ted has 15 issued and 15 pending patents and contributes to several Apache open source projects including Hadoop, Zookeeper and Hbase. He is also a committer for Apache Mahout. Ted earned a BS degree in electrical engineering from the University of Colorado; a MS degree in computer science from New Mexico State University; and a Ph.D. in computing science from Sheffield University in the United Kingdom. Ted also bought the drinks at one of the very first Hadoop User Group meetings.
Some TriHUG members are in the early stage of putting together an all day hackathon on all things scaling (Hadoop, Cassandra, Hive, Pig, Mahout, etc.) and wanted to get some info out to the community as well as a call for volunteers and sponsors.
The basic gist of the day is that we get together and spend the day hacking and learning about writing scalable, fault tolerant systems. All ranges of experience are welcome and we fully expect that one of the groups that forms will be a “tutorial” group, while other groups will be doing more advanced things. The key is to get lots of interaction and cross-fertilization of ideas.
Our tentative plan is that we will make available:
1. Compute Cluster time (likely Amazon EC2) along with ready to use instances w/ appropriate things already installed. (More later)
2. Some public data sets, but feel free to bring your own publicly available on Amazon S3
3. Food, drinks, etc. including pizza/beer at the end
4. Network connectivity
5. Space to work in
6. (TBD) Machine to submit jobs using a fair scheduler
You need to bring your laptop and an open mind. Also having your favorite tools on your machine would be good. A github account or something similar would also be useful.
Our likely date for this is June 18th with a backup date of June 25 (pending space availability) from 9 AM - 6 (?) PM. Attendance will require RSVP and we will send out sign up info later. For now, we are targeting it to be free (including EC2 compute time), but that is predicated on us getting sponsorships to cover costs, so if you think you or your company can sponsor, please let us know ASAP.
Tentative Schedule (strawman):
8:30: Doors open/networking/coffee/snacks
9 - 9:30: Idea pitches and Seed Projects announced and teams formed — people can stand up and say what they are interested in and then we imagine people can team up based on their interest — for instance, I will probably work on Mahout and machine learning
9:30 - 12: Hack
12-1: Food/networking/hacking
1-5(?): Hack
5-6 (no firm cut off time): Share what you learned to the group over pizza and drinks. Demo if you have one.
How you can help:
- Help us get data sets organized and a Chef/Puppet recipe setup with all the appropriate tools/languages/SCM/etc. Also, think of interesting problems to work on.
- Sponsor food/coffee/drinks/t-shirts/compute time/ etc. Please contact Grant Ingersoll at info@trihug.org. I don’t think we are talking about a super lot of money here (maybe $1000-1500 total? — more on this as things develop)
- Let us know you are interested, the more we hear from sooner, the better we can plan space accordingly. Please reply on this list if you are interested.
- Are you graphically capable? Help us design a t-shirt.
- Once we firm up some details, help us spread the word
