spark.addFile: Add a file or directory to be downloaded with this Spark job...

In SparkR: R Front End for 'Apache Spark'

Description

The path passed can be either a local file, a file in HDFS (or other Hadoop-supported filesystems), or an HTTP, HTTPS or FTP URI. To access the file in Spark jobs, use spark.getSparkFiles(fileName) to find its download location.

Usage

spark.addFile(path, recursive = FALSE)

Arguments

path	The path of the file to be added
recursive	Whether to add files recursively from the path. Default is FALSE.

Details

A directory can be given if the recursive option is set to true. Currently directories are only supported for Hadoop-supported filesystems. Refer Hadoop-supported filesystems at https://cwiki.apache.org/confluence/display/HADOOP2/HCFS.

Note: A path can be added only once. Subsequent additions of the same path are ignored.

Note

spark.addFile since 2.1.0
