> Infra for R - need qpdf on Jenkins
> ----------------------------------

> Key: SPARK-18347
> URL: https://issues.apache.org/jira/browse/SPARK-18347
> Project: Spark
> Issue Type: Bug
> Components: SparkR
> Affects Versions: 2.1.0
> Reporter: Felix Cheung
> Assignee: shane knapp
>
> As a part of working on building R package
> (https://issues.apache.org/jira/browse/SPARK-18264) we discover that building
> the package and vignettes require a tool call qpdf (for compressing PDFs)
> In R, it is looking for qpdf as such:
> {code}Sys.which(Sys.getenv("R_QPDF", "qpdf")){code}
> ie. which qpdf or whatever the export R_QPDF is pointing to.
> Otherwise it raises a warning as such:
> {code}
> * checking for unstated dependencies in examples ... OK
> WARNING
> ‘qpdf’ is needed for checks on size reduction of PDFs
> {code}
