             Summary: Skip SparkR tests when missing Hadoop winutils on CRAN windows machines
                 Key: SPARK-20727
                 URL: https://issues.apache.org/jira/browse/SPARK-20727
             Project: Spark
          Issue Type: Bug
          Components: SparkR
    Affects Versions: 2.1.1, 2.2.0
            Reporter: Shivaram Venkataraman


We should skips tests that use the Hadoop libraries while running
on CRAN check with Windows as the operating system. This is to handle
cases where the Hadoop winutils binaries are not available on the target
system. The skipped tests will consist of
1. Tests that save, load a model in MLlib
2. Tests that save, load CSV, JSON and Parquet files in SQL
3. Hive tests

Note that these tests will still be run on AppVeyor for every PR, so our overall test coverage should not go down
