Currently, we are using Mesos 0.27.0. The master is build up with a Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz CPU and a 4GB RAM. The slave (Banana PI) is build up with a Cortex -A7 Dual-Core CPU and a 1GB RAM.
By using the Mesos API, we have developed and completed the execution of the framework which is based on python.
but, we found that it takes too much time between the messages, 'Forked child with pid' and 'Got registration for executor' from the slave log. (5sec)
If you know how to deal with this problem, please let us know.
