  1. Wait about 5 minutes for completion (each drone will receive shutdown cmd).

CSV-files

Project contains following csv files:

  • stations.csv - list of tube stations with coordinates
  • drones.csv - list of drones with initial coordinates
  • commands.csv - list of commands and times

Those files are read at startup.

Notes

  • Drones runs in real-time, however time is adjusted to the time of first command during Dispatcher startup.
  • No 10 cmd requirement implemented. This is JVM program. I see no reason for that limit.
  • No unit tests implemented. The time for the assignment was limited. If it's required to see my unit tests, please see my github account - https://github.com/dmitrypekar?tab=activity kafka-mesos project contains a lot of unit-tests.
  • Added Idea files for convenience
