After submitting a COMPSs application I have received the following error message and the application is not executed.

This error often occurs when: You provide no hostname or an invalid hostname to the Compass connect dialog. The destination server rejects a connection on an incorrect port. Your MongoDB cluster or server has been shutdown or the server hostname has changed.
If you have created a user and are having trouble authenticating, try the following: Check that you are using the correct username and password for your database user, and that you are connecting to the correct database deployment. Check that you are specifying the correct authSource database in your connection string.
The use of SRV records eliminates the requirement for every client to pass in a complete set of state information for the cluster. Instead, a single SRV record identifies all the nodes associated with the cluster (and their port numbers) and an associated TXT record defines the options for the URI.
You are trying to run master and worker in the same node. COMPSs 1.3 at cluster with the NIO adaptor (default option) is using mpirun to spawn the master and worker processes in the different nodes of the cluster and the mpirun installed in the cluster doesn't allow to do this.
The options to solve it are the following:
Next COMPSs software release will use the spawn command which is available in the different cluster resource managers( such as blaunch, srun) which must solve this issue
