Hive Tables

将HIVE_HOME/conf/

hive-site.xml

文件copy到SPARK_HOME/conf/下

When not configured by the hive-site.xml, the context automatically creates

metastore_db

and

warehouse

in
the current directory.

// sc is an existing SparkContext.
val sqlContext = new org.apache.spark.sql.hive.HiveContext(sc)

sqlContext.sql("CREATE TABLE IF NOT EXISTS src (key INT, value STRING)")
sqlContext.sql("LOAD DATA LOCAL INPATH 'examples/src/main/resources/kv1.txt' INTO TABLE src")

// Queries are expressed in HiveQL
sqlContext.sql("FROM src SELECT key, value").collect().foreach(println)
