一 环境信息

1.1 组件版本

组件	版本
Spark	3.2.3
Hudi	0.14.0
Zeppelin	0.11.0-SNAPSHOT

1.2 环境准备

1. Zeppelin 整合 Spark 参考：Apache Zeppelin 一文打尽
2. Hudi0.14.0编译参考：Hudi0.14.0 最新编译

二 整合 Spark 和 Hudi

2.1 配置

%spark.conf

SPARK_HOME /usr/lib/spark

# set execution mode
spark.master yarn
spark.submit.deployMode client

# --jars
spark.jars /root/app/jars/hudi-spark3.2-bundle_2.12-0.14.0.jar

# --conf
spark.serializer org.apache.spark.serializer.KryoSerializer
spark.sql.catalog.spark_catalog org.apache.spark.sql.hudi.catalog.HoodieCatalog
spark.sql.extensions org.apache.spark.sql.hudi.HoodieSparkSessionExtension
spark.kryo.registrator org.apache.spark.HoodieSparkKryoRegistrar

Specifying yarn-client & yarn-cluster in spark.master is not supported in Spark 3.x any more, instead you need to use spark.master and spark.submit.deployMode together.

Mode	spark.master	spark.submit.deployMode
Yarn Client	yarn	client
Yarn Cluster	yarn	cluster

2.2 导入依赖

%spark
import scala.collection.JavaConversions._
import org.apache.spark.sql.SaveMode._
import org.apache.hudi.DataSourceReadOptions._
import org.apache.hudi.DataSourceWriteOptions._
import org.apache.hudi.common.table.HoodieTableConfig._
import org.apache.hudi.config.HoodieWriteConfig._
import org.apache.hudi.keygen.constant.KeyGeneratorOptions._
import org.apache.hudi.common.model.HoodieRecord
import spark.implicits._

2.3 插入数据

%spark
val tableName = "trips_table"
val basePath = "hdfs:///tmp/trips_table"
val columns = Seq("ts","uuid","rider","driver","fare","city")
val data =
  Seq((1695159649087L,"334e26e9-8355-45cc-97c6-c31daf0df330","rider-A","driver-K",19.10,"san_francisco"),
    (1695091554788L,"e96c4396-3fad-413a-a942-4cb36106d721","rider-C","driver-M",27.70 ,"san_francisco"),
    (1695046462179L,"9909a8b1-2d15-4d3d-8ec9-efc48c536a00","rider-D","driver-L",33.90 ,"san_francisco"),
    (1695516137016L,"e3cf430c-889d-4015-bc98-59bdce1e530c","rider-F","driver-P",34.15,"sao_paulo"    ),
    (1695115999911L,"c8abbe79-8d89-47ea-b4ce-4d224bae5bfa","rider-J","driver-T",17.85,"chennai"));

var inserts = spark.createDataFrame(data).toDF(columns:_*)
inserts.write.format("hudi").
  option(PARTITIONPATH_FIELD_NAME.key(), "city").
  option(TABLE_NAME, tableName).
  mode(Overwrite).
  save(basePath)

2.3 查询数据

%spark
val tripsDF = spark.read.format("hudi").load(basePath)
tripsDF.createOrReplaceTempView("trips_table")
spark.sql("SELECT uuid, fare, ts, rider, driver, city FROM  trips_table WHERE fare > 20.0").show()

结果：

+--------------------+-----+-------------+-------+--------+-------------+
|                uuid| fare|           ts|  rider|  driver|         city|
+--------------------+-----+-------------+-------+--------+-------------+
|e96c4396-3fad-413...| 27.7|1695091554788|rider-C|driver-M|san_francisco|
|9909a8b1-2d15-4d3...| 33.9|1695046462179|rider-D|driver-L|san_francisco|
|e3cf430c-889d-401...|34.15|1695516137016|rider-F|driver-P|    sao_paulo|
+--------------------+-----+-------------+-------+--------+-------------+
