Review comment:
Actually in my scenario
```
sparkLauncher.setConf("spark.executor.instances", executors);
sparkLauncher.setConf(SparkLauncher.EXECUTOR_MEMORY, executorMemory);
sparkLauncher.setConf(SparkLauncher.DRIVER_MEMORY, driverMemory );
sparkLauncher.setConf(SparkLauncher.EXECUTOR_CORES, executorCores);
```
There is no option in SparkLauncher for executors.
