Hello,

Here are the scheduler command line options (based on example given)
https://github.com/apache/incubator-aurora/blob/master/examples/scheduler/scheduler-local.sh

-http_port=8081
-mesos_master_address=zk://cdh4master01.preprod:2181,cdh4master02.preprod:2181,cdh4worker01.preprod:2181/mesos
-zk_endpoints=cdh4master01.preprod:2181,cdh4master02.preprod:2181,cdh4worker01.preprod:2181
-cluster_name=preprod -native_log_quorum_size=1
-native_log_election_retries=2 -serverset_path=/aurora/scheduler
-native_log_zk_group_path=/aurora/replicated-log
-native_log_file_path=/tmp/aurora-scheduler/db
-backup_dir=/tmp/aurora-scheduler/backups
-thermos_executor_path=/dev/null -gc_executor_path=/dev/null -vlog=INFO
-logtostderr

Does this wouldn't allow 1 instance running to be enough ?
