yuhao yang updated SPARK-5243:
------------------------------
Description:
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 and better fix
options.

I am preparing PR for the case. And I would like to know your opinions about if
a fix is needed and better fix options.
