Using TestHiveContext/HiveContext in unit tests

[Sahil Sareen]

I'm trying to do this in unit tests:

    val sConf = new SparkConf()
      .setAppName("RandomAppName")
      .setMaster("local")
    val sc = new SparkContext(sConf)
    val sqlContext = new TestHiveContext(sc)  // tried new HiveContext(sc)
as well


But I get this:

*[scalatest] **Exception encountered when invoking run on a nested suite -
java.lang.RuntimeException: Unable to instantiate
org.apache.hadoop.hive.metastore.HiveMetaStoreClient *** ABORTED ****

*[scalatest]   java.lang.RuntimeException: java.lang.RuntimeException:

The code works perfectly when I run using spark-submit, but not in unit
tests. Any inputs??
