Run spark unit test on Windows 7

[Konstantin Kudryavtsev]

Hi all,

I'm trying to run some transformation on *Spark*, it works fine on cluster
(YARN, linux machines). However, when I'm trying to run it on local machine
(*Windows 7*) under unit test, I got errors:

java.io.IOException: Could not locate executable null\bin\winutils.exe
in the Hadoop binaries.
at org.apache.hadoop.util.Shell.getQualifiedBinPath(Shell.java:318)
at org.apache.hadoop.util.Shell.getWinUtilsPath(Shell.java:333)
at org.apache.hadoop.util.Shell.<clinit>(Shell.java:326)
at org.apache.hadoop.util.StringUtils.<clinit>(StringUtils.java:76)
at org.apache.hadoop.security.Groups.parseStaticMapping(Groups.java:93)


My code is following:

@Test
def testETL() = {
    val conf = new SparkConf()
    val sc = new SparkContext("local", "test", conf)
    try {
        val etl = new IxtoolsDailyAgg() // empty constructor

        val data = sc.parallelize(List("in1", "in2", "in3"))

        etl.etl(data) // rdd transformation, no access to SparkContext or Hadoop
        Assert.assertTrue(true)
    } finally {
        if(sc != null)
            sc.stop()
    }
}


Why is it trying to access hadoop at all? and how can I fix it? Thank you
in advance

Thank you,
