Kraken

• Project: https://www.mediawiki.org/wiki/Analytics/Kraken
• Kraken Dataflow Diagram: http://upload.wikimedia.org/wikipedia/mediawiki/3/38/Kraken_flow_diagram.png

• CDH4 — the world's leading Apache Hadoop Distribution. http://www.cloudera.com/content/cloudera/en/products/cdh.html
  • The Hadoop Distributed File System ( HDFS ) is a distributed file system designed to run on commodity hardware. http://hadoop.apache.org/docs/hdfs/current/hdfs_design.html
• Hue is a general purpose web interface built for the Hadoop ecosystem. Use Hue if you want to easily run and schedule Pig and Hive jobs.
  • Navigate to to http://hue.analytics.wikimedia.org/. You'll need a Hue login account. Otto should have created one for you and given you a password if you also asked him for a shell account earlier. (This will soon be hooked into LDAP, and you will be able to use your usual WMF password).

• On Storm:
  • We brought in Nathan Marz, creator of Storm, as part of the WMF Analytics Day. He provided useful feedback during the research phase, which encouraged us to examine Storm as a solution for the ETL/Stream Processing phase.
