             Summary: lint-r fails if lint-r.R installs any new packages
                 Key: SPARK-22415
                 URL: https://issues.apache.org/jira/browse/SPARK-22415
             Project: Spark
          Issue Type: Bug
          Components: Tests
    Affects Versions: 2.3.0
         Environment: OSX 10.12.6 R 3.4.2
            Reporter: Joel Croteau
            Priority: Minor


The dev/lint-r script checks for lint failures by seeing if anything is output to stdout by lint-r.R. Since package installations will often produce output to stdout, this will cause it to report a failure even if lint-r.R succeeded. This would also mean that if there were a failure further up in lint-r.R that output a message to stderr, it would not detect this and think lint-r.R had succeeded. It would be preferable for lint-r.R to output lints to stderr and for lint-r to check that and/or for lint-r.R to return a failure code if there are any lints, which lint-r could check for. I will write a patch to do this.
