>             Project: Spark
>          Issue Type: Bug

> Currently we have R worker process launched with the --vanilla option that brings it up in a clean state (without init profile or workspace data, https://stat.ethz.ch/R-manual/R-devel/library/base/html/Startup.html). However, the R process for the Spark driver is not.
> We should do that because
> 1. That would make driver consistent with the worker process in R - for instance, a library would not be load in driver but not worker
> 2. Since SparkR depends on .libPath and .First() it could be broken by something in the user workspace, for example
> Here are the changes proposed:
> 1. When starting `sparkR` shell (except: allow save/restore workspace, since the driver/shell is local)
> 2. When launching R driver in cluster mode
> 3. In cluster mode, when calling R to install shipped R package
