is there a way to check if a Map/Reduce script is currently running? Use case is a user-event script will trigger the execution of the map/reduce script but it has to know if the script is already running, I am getting theMAP_REDUCE_ALREADY_RUNNING error

Check out the N/task API, specifically: task.MapReduceScriptTaskStatus

thanks

Another approach is putting the task.submit() inside a try/catch, and if that error raises, simply ignore it (or log it).

You can also run saved searches on running Map Reduce instances (

search.Type.SCHEDULED_SCRIPT_INSTANCE

)
