2) will be ideal but given the velocity of main branch, what Mesos ended up doing was simply having a separate repo since it will take too long to merge back to main. We ended up running it pre-release (or major PR merged) and not on every PR, I will also comment on asking users to run it. We

Hi Chawla, One possible reason is that Mesos fine grain mode also takes up cores to run the executor per host, so if you have 20 agents running Fine grained executor it will take up 20 cores while it's still running. Tim On Fri, Dec 16, 2016 at 8:41 AM, Chawla,Sumit

Yes if want to manually override what IP to use to be contacted by the master you can set LIPROCESS_IP and LIBPROCESS_PORT. It is a Mesos specific settings. We can definitely update the docs. Note that in the future as we move to use the new Mesos Http API these configurations won't be needed

Hi Gidon, 1. Yes, each Spark application is wrapped in a new Mesos framework. 2. In fine grained mode, what happens is that Spark scheduler specifies a custom Mesos executor per slave, and each Mesos task is a Spark executor that will be launched by the Mesos executor. It's hard to determine
