There needs to be at least one exec host for jobs to actually run, irrespective of whether auto-scaling is on or off.
In an attempt to offload work from the master instance when there are workers, CloudMan will automatically toggle the master as an exec host a the first worker is added or the last one removed. However, I'm starting to think there's a bug in how that's implemented. If this causes you more problems, let us know.
