Set the SPARK_HOME environment variable. This slightly speeds up some operations, including the connection time.

spark_home_set(path = NULL, ...)



A string containing the path to the installation location of Spark. If NULL, the path to the most latest Spark/Hadoop versions is used.


Additional parameters not currently used.


The function is mostly invoked for the side-effect of setting the SPARK_HOME environment variable. It also returns TRUE if the environment was successfully set, and FALSE otherwise.


if (FALSE) { # Not run due to side-effects spark_home_set() }
