运行spark 官方hive范例的完整记录

2019年6月7日 437次阅读来源: DONG999

sample java:
org.apache.spark.examples.sql.hive.JavaSparkHiveExample

几处修改：

   SparkSession spark = SparkSession
      .builder()
      .appName("Java Spark Hive jar Example")
      //.master("spark://hadoopnode3:7077")
      .config("spark.executor.memory", "512m")
      //.config("spark.sql.warehouse.dir", warehouseLocation)
      .enableHiveSupport()
      .getOrCreate();

    spark.sql("use myhive");
    spark.sql("CREATE TABLE IF NOT EXISTS src (key INT, value STRING)");
    //spark.sql("LOAD DATA LOCAL INPATH 'resources/kv1.txt' INTO TABLE src");
    spark.sql("LOAD DATA INPATH '/resources/kv1.txt' INTO TABLE src");

kv1.txt 是个简单的2列数据，空格分开，执行后会自动删除。

1. eclipse java 搭建

image.png

2. export to jar file from eclipse

a. 右键点击该java file，并导出export to a jar file: hiveTesting.jar

b. 上传范例需要的txt or json 等文件

hadoop fs -put ./resources /resources

3. upload to one testbed on hadoop cluster

/tmp/hiveTesting.jar

spark submit

 spark-submit --class org.apache.spark.examples.sql.hive.JavaSparkHiveExample --master spark://hadoopnode3:7077 /tmp/hiveTesting.jar

因为有个hadoop node关了，就直接指定了 — master 机器，没有使用 yarn cluster.
