Mesos doesn't store task information in ZooKeeper. It is stored in Mesos master's memory and recovered from Mesos agents after a master restart / leader election.
The task history can be controlled by `max_completed_frameworks`, `max_completed_tasks_per_framework` master flags. AFAICT, the completed frameworks/executors/tasks information is recovered too from the agents after a master failover. Are you not seeing them after a master failover? Which version are you running?

I hope, mesos uses Zookeeper to store the task History. We lost > history sometimes when we restart mesos. Does it store in memory?
