Ran Mingxuan updated SPARK-22560:
---------------------------------
Description:
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("testApp");
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}
