             Summary: Must create spark session directly to connect to hive
                 Key: SPARK-22560
                 URL: https://issues.apache.org/jira/browse/SPARK-22560
             Project: Spark
          Issue Type: Bug
          Components: Java API, SQL
    Affects Versions: 2.1.0
            Reporter: Ran Mingxuan


I have built a spark job like below:

{code:java}
// wrong code
public void main(String[] args)
{
    SparkConf sparkConf = new SparkConf().setAppName("testApp");
    JavaSparkContext sc = new JavaSparkContext(sparkConf);
    
sc.hadoopConfiguration().setBoolean("mapreduce.fileoutputcommitter.marksuccessfuljobs",
 false);
    sc.hadoopConfiguration().setBoolean("parquet.enable.summary-metadata", 
false);//
    SparkSession spark = 
SparkSession.builder().sparkContext(sc.sc()).enableHiveSupport().getOrCreate();
    spark.sql("show databases").show();
}
{code}

and with this code spark job will not be able to find hive meta-store even it 
can discover correct warehouse.

I have to use code like below to make things work:

{code:java}
// correct code 
public String main(String[] args)
{
    SparkConf sparkConf = new SparkConf().setAppName("nice_clean");
    SparkSession spark = 
SparkSession.builder().config(sparkConf).enableHiveSupport().getOrCreate();
    SparkContext sparkContext = spark.sparkContext();
    JavaSparkContext sc = JavaSparkContext.fromSparkContext(sparkContext);
    
sc.hadoopConfiguration().setBoolean("mapreduce.fileoutputcommitter.marksuccessfuljobs",
 false);
    sc.hadoopConfiguration().setBoolean("parquet.enable.summary-metadata", 
false);
    spark.sql("show databases").show();
}
{code}
