Title: fix spark.yarn.max.executor.failures explaination

According to
'''scala
private val maxNumExecutorFailures = sparkConf.getInt("spark.yarn.max.executor.failures",
sparkConf.getInt("spark.yarn.max.worker.failures", math.max(args.numExecutors * 2, 3)))
''''
default value should be numExecutors * 2, with minimum of 3, and it's same to the config
`spark.yarn.max.worker.failures`
