Hi Brian,
At this point you should see the TT attempting to be launched via Mesos. The "launched but not heartbeat yet" count tells us that the framework has accepted resources for 4 slots but the TT hasn't actually come up yet. Do you see the task in your Meaos cluster UI, and is there anything interesting in the task logs? -- Tom Arnfeld Developer // DueDil (+44) 7525940046 25 Christopher Street, London, EC2A 2BS On Thu, May 7, 2015 at 12:01 PM, Brian Topping <[email protected]> wrote: > Thanks guys, this was helpful.
