Junyang Qian commented on SPARK-16579:
--------------------------------------
If we find Spark home and the JARs missing, do we want to still install to a
cache dir and then redirect Spark home to that dir?
> Add a spark install function
> ----------------------------

> Key: SPARK-16579
> URL: https://issues.apache.org/jira/browse/SPARK-16579
> Project: Spark
> Issue Type: Sub-task
> Components: SparkR
> Reporter: Shivaram Venkataraman
> Assignee: Junyang Qian
>
> As described in the design doc we need to introduce a function to install
> Spark in case the user directly downloads SparkR from CRAN.
> To do that we can introduce a install_spark function that takes in the
> following arguments
> {code}
> hadoop_version
> url_to_use # defaults to apache
> local_dir # defaults to a cache dir
> {code}
> Further more I think we can automatically run this from sparkR.init if we
> find Spark home and the JARs missing.
