> *Previously it was:*
> 1. the value of spark memory is equal 75% from total (if instance shape is
> up to 8 GB)
> 2. the value of spark.executor.memory is equal formula value: total value
> minus 3.5 GB (if instance shape is over than 8 GB).
> *Currently it is:*
> +Case 1:+ Rstudio [4 GB]
> 3.4*0.75*1024=3072MB (by theory)
> But by practical:
