  • Room: CIT 345
  • Title: "HDFS Quorum-Journal"
  • Abstract:
Todd will present an overview of his recent work on the HDFS NameNode to make it highly available by synchronizing multiple replicas via a distributed, quorum-based protocol. While not required, some background understanding of distributed algorithms (such as Paxos) will be helpful. For complete details, the design document for this protocol can be found here: http://tiny.cloudera.com/qjm-design
