Hi Alex, See my answers below
1. Launch a task without accepting an offer (on already existing executor). > This is not currently possible. Every task needs some non-zero resources, and hence an offer, to be launched. What's your use case? > 2. Initiate an executor with no tasks (to launch them later). > The only way to do it is to a launch an executor with dummy task. If you are writing your own executor, you can interpret the dummy task as you wish (e.g., no-op). There is no API to launch an executor without a task yet. > 3. How actually to introduce your own executor with V1 protocol. > See the executor API doc <http://mesos.apache.org/documentation/latest/scheduler-http-api/> on how to write one. Once your executor binary exists, upload it in a storage location somewhere (hdfs, http server etc) and pass it's location as URI in ExecutorInfo. See example here <https://github.com/apache/mesos/blob/master/src/examples/java/V1TestFramework.java> .
