>             Project: Spark
>          Issue Type: Improvement
>          Components: Deploy
>    Affects Versions: 1.2.0
>         Environment: centos, others should be similar
>            Reporter: yuhao yang

> Spark will hang if calling spark-submit under the conditions:
> 1. the cluster has only one worker.
> 2. driver memory + executor memory > worker memory
> 3. deploy-mode = cluster
> This usually happens during development for beginners.
> There should be some exit mechanism or at least a warning message in the output of the spark-submit.
> I would like to know your opinions about if a fix is needed (is this by design?) and better fix options.
