Spark should fail fast if initial memory too large(set by "spark.executor.extraJavaOptions") for executor to start

if you set initial memory(set by "spark.executor.extraJavaOptions=-Xms{XXX}G" ) larger than maximum memory(set by "spark.executor.memory")

Eg.

     spark.executor.memory=1G

     spark.executor.extraJavaOptions=-Xms2G

from the driver process you just see executor failures with no warning, since the more meaningful errors are buried in the executor logs. 

Eg., on Yarn, you see:

Error occurred during initialization of VM
Initial heap size set to a larger value than the maximum heap size

Instead we should just fail fast with a clear error message in the driver logs.
