The Hadoop Server Layer

The tests mapped to this layer do the following:

  • Monitors queues spawned by the YARN scheduler and tracks the status of jobs running in each queue;
  • Monitors the users running Map Reduce jobs and reports the status of these jobs per user;
  • Monitors the shuffling process and reports the number and nature of errors encountered in the process
