[SPARK-10332][CORE] Fix yarn spark executor validation
From Jira:
Running spark-submit with yarn with number-executors equal to 0 when not
using dynamic allocation should error out.
In spark 1.5.0 it continues and ends up hanging.
yarn.ClientArguments still has the check so something else must have
changed.
spark-submit --master yarn --deploy-mode cluster --class
org.apache.spark.examples.SparkPi --num-executors 0 ....
spark 1.4.1 errors with:
java.lang.IllegalArgumentException:
Number of executors was 0, but must be at least 1
(or 0 if dynamic executor allocation is enabled).
