Hi, 

I'm following the Quickstart instructions, but the local Flink cluster doesn't start up correctly. The web frontend is available at http://localhost:8081, but shows 0 Task Managers, 0 Task Slots and 0 Available Task Slots. 

This error message appears in the taskexecutor logs after running ./bin/start-cluster.sh: 

INFO  org.apache.flink.runtime.taskexecutor.TaskExecutor - Could not resolve ResourceManager address akka.tcp://flink@localhost:6123/user/resourcemanager, retrying in 10000 ms: Ask timed out on [ActorSelection[Anchor(akka.tcp://flink@localhost:6123/), Path(/user/resourcemanager)]] after [10000 ms]. Sender[null] sent message of type "akka.actor.Identify"..

I installed Flink via 'brew install apache-flink' and the version number is 1.6.2.

Any help would be greatly appreciated in getting me up and running. 

Thanks
