As far as I know, only yarn mode can set --num-executors, someone proved to set more number-execuotrs for will perform better than set only 1 or 2 executor with large mem and core. sett http://apache-spark-user-list.1001560.n3.nabble.com/executor-cores-vs-num-executors-td9878.html
Why Standalone mode not provide "number-execuotrs" parameters instead of using spreadout strategy by default to generate executor? Can anyone explain this in detail ?
