First 10 Cisco boxes are available. Just puppetized a generic Java installation.

Testing and benchmarking different hadoop parameters. Using TestDSFIO and Terasort benchmarks. Learning!

Cluster planning continues smoothly: David Schoonover has begun writing architecture and dataflow documentation. Cluster setup began in earnest mid-month when the Operations team delivered 10 machines from a 2011 Cisco hardware grant. Andrew Otto and David set up the systems, user environments, and software dependencies. They began begin testing Cassandra, Hadoop, and Hbase, to evaluate which best meets the storage needs of the cluster's batch and stream processing systems.

At the Berlin Hackathon, Diederik van Liere and Dave Schoonover gathered community input on analytics plans, and gave a few ad hoc presentations about the upcoming changes to the data-processing workflow.

Andrew Otto has performed several preliminary benchmarks on a 10 node CDH3 cluster. We plan to do more benchmarking with CDH 4 and Datastax Enterprise.

Focused has recently switched to building, testing and deploying Facebook's scribe as an eventual replacement for udp2log. We are investigating the use of scribe initially for Lucene search query logging.

Researching and evaluating udp2log replacements for getting data into Kraken cluster. Document in progress here: Analytics/Distributed_Logging_Solutions.

<section begin="2012-08-monthly"/>Otto and Dave concluded their research into distributed logging systems to replace  for Kraken; we'd like to believe the proposal is technical-yet-readable, with a rough charm and boundless love &mdash; much like all engineering.<section end="2012-08-monthly"/>

2012-09-monthly
<section begin="2012-09-monthly"/>After experimenting with DataStax Enterprise, the team came to consensus that they need to use fully open-source software and ruled it out in favor of CDH4. They also experimented with PigLatin and are developing a script to geocode and count requests per country for the Fundraising team. Analytics Ciscos were reinstalled with Ubuntu Precise.<section end="2012-09-monthly"/>

2012-10-monthly
<section begin="2012-10-monthly"/>The Analytics team has been working on: configuring and puppetizing CDH4 (Hue, Sqoop, Oozie, Zookeeper, Hive, Pig), configuring and puppetizing Kafka, benchmarking performance, drafting metadata schemas, setting up ganglia monitoring, setting up prototype pixel service endpoint, and running ad-hoc data queries for fundraising.<section end="2012-10-monthly"/>
