          Mário Almeida
            Umit Cavus
         Strahinja Lazetic

      Supervisor: Jim Dowling
Aim
High Availability in YARN
Aim
HA with ZooKeeper
Aim
HA with NDB
Outcome
● Highly Available implementation of YARN
  ○ with Zookeeper before the hadoop team
  ○ with NDB MySql-Cluster before Jim kicks us out


● (Secondary goal) make RM stateless so we
  can have more than one running at each
  moment.
  ○ So we can have failover when there is failure in a
    RM


● (Eventual goal) Get a job!
