Description

Currently GitHub Actions builds are failed as below:

ERROR: this R is version 3.4.4, package 'SparkR' requires R >= 3.5
[error] running /home/runner/work/spark/spark/R/install-dev.sh ; received return code 1
##[error]Process completed with exit code 10.

Looks GitHub Actions has R 3.4.4 installed by default; however, R 3.4 was dropped as of SPARK-32073. When SparkR tests are not needed, GitHub Actions does not install R 3.6 and it caused the test failure.

In fact, SparkR is installed in case of running R linter, see SPARK-8505; however, we don't run the linters in test-only mode at testing script.

We can safely skip it in test-only mode in our testing script.
