I am using mesos for container orchestration and get task history from mesos using */task* endpoint.
Mesos is running in a 7 nodes cluster and zookeeper is running in a 3 node cluster. I hope, mesos uses Zookeeper to store the task History. We lost history sometimes when we restart mesos. Does it store in memory? I am trying to understand what is happening here. My questions are, 1. Where does it store task histories? 2. How can we configure the task history cleanup policy? 3. Why do we loose complete task history on restarting mesos?
