    The problem that occurred was that JM bound the IP:PORT with some delay, so 
TMs failed to start, since they couldn't connect.
    
    When i tried in 5-node environment, sometimes 2 or 3 TMs failed because JM 
wasn't ready there. There was no subsequential checking done, TMs just stopped. 
I agree that TM should indeed try to check several times, if the JM is 
available, so i will try to look at it also.

>             Project: Flink
>          Issue Type: Bug
>          Components: Distributed Runtime
>    Affects Versions: 0.9, 0.8.1
>         Environment: Linux
>            Reporter: Lukas Raska
>            Priority: Minor
>   Original Estimate: 5m
>  Remaining Estimate: 5m
>
> When starting Flink cluster via start-cluster.sh script, JobManager startup 
> can be delayed (as it's started asynchronously), which can result in failed 
> startup of several task managers.
> Solution is to wait certain amount of time and periodically check if RPC port 
> is accessible, then proceed with starting task managers.
