I'm trying to write a test for spark application, but I get this Exception when trying to run the next test
class BasicIT {
val sparkConf: SparkConf = new SparkConf().setAppName("basic.phase.it").setMaster("local[1]")
var context:SparkContext = new SparkContext(sparkConf)
@Test
def myTest(): Unit = {
print("test")
}
}
fails with this exception:
2016-07-24 21:04:39,956 [main,95] ERROR SparkContext - Error initializing SparkContext.
