SparkR CRAN Release

To release SparkR as a package to CRAN, we would use the devtools package. Please work with the dev@spark.apache.org community and R package maintainer on this.

Release

First, check that the Version: field in the pkg/DESCRIPTION file is updated. Also, check for stale files not under source control.

Note that while check-cran.sh is running R CMD check, it is doing so with --no-manual --no-vignettes, which skips a few vignettes or PDF checks - therefore it will be preferred to run R CMD check on the source package built manually before uploading a release.

To upload a release, we would need to update the cran-comments.md. This should generally contain the results from running the check-cran.sh script along with comments on status of all WARNING (should not be any) or NOTE. As a part of check-cran.sh and the release process, the vignettes is build - make sure SPARK_HOME is set and Spark jars are accessible.

Once everything is in place, run in R under the SPARK_HOME/R directory:

paths <- .libPaths(); .libPaths(c("lib", paths)); Sys.setenv(SPARK_HOME=tools::file_path_as_absolute("..")); devtools::release(); .libPaths(paths)

For more information please refer to http://r-pkgs.had.co.nz/release.html#release-check

Testing: build package manually

To build package manually such as to inspect the resulting .tar.gz file content, we would also use the devtools package.

Source package is what get released to CRAN. CRAN would then build platform-specific binary packages from the source package.

Build source package

To build source package locally without releasing to CRAN, run in R under the SPARK_HOME/R directory:

paths <- .libPaths(); .libPaths(c("lib", paths)); Sys.setenv(SPARK_HOME=tools::file_path_as_absolute("..")); devtools::build("pkg"); .libPaths(paths)

(http://r-pkgs.had.co.nz/vignettes.html#vignette-workflow-2)

Similarly, the source package is also created by check-cran.sh with R CMD build pkg.

For example, this should be the content of the source package:

DESCRIPTION	R		inst		tests
NAMESPACE	build		man		vignettes

inst/doc/
sparkr-vignettes.html
sparkr-vignettes.Rmd
sparkr-vignettes.Rman

build/
vignette.rds

man/
 *.Rd files...

vignettes/
sparkr-vignettes.Rmd

Test source package

To install, run this:

R CMD INSTALL SparkR_2.1.0.tar.gz

With "2.1.0" replaced with the version of SparkR.

This command installs SparkR to the default libPaths. Once that is done, you should be able to start R and run:

library(SparkR)
vignette("sparkr-vignettes", package="SparkR")

Build binary package

To build binary package locally, run in R under the SPARK_HOME/R directory:

paths <- .libPaths(); .libPaths(c("lib", paths)); Sys.setenv(SPARK_HOME=tools::file_path_as_absolute("..")); devtools::build("pkg", binary = TRUE); .libPaths(paths)

For example, this should be the content of the binary package:

DESCRIPTION	Meta		R		html		tests
INDEX		NAMESPACE	help		profile		worker
