QuickStart

  1. download and compile Spark Doris Connector from https://github.com/apache/doris-spark-connector, we suggest compile Spark Doris Connector by Doris offfcial image。
$ docker pull apache/doris:build-env-ldb-toolchain-latest
  1. the result of compile jar is like:spark-doris-connector-3.1_2.12-1.0.0-SNAPSHOT.jar

  2. download spark for https://spark.apache.org/downloads.html .if in china there have a good choice of tencent link https://mirrors.cloud.tencent.com/apache/spark/spark-3.1.2/

#download
wget https://mirrors.cloud.tencent.com/apache/spark/spark-3.1.2/spark-3.1.2-bin-hadoop3.2.tgz
#decompression
tar -xzvf spark-3.1.2-bin-hadoop3.2.tgz
  1. config Spark environment
vim /etc/profile
export SPARK_HOME=/your_parh/spark-3.1.2-bin-hadoop3.2
export PATH=$PATH:$SPARK_HOME/bin
source /etc/profile
  1. copy spark-doris-connector-3.1_2.12-1.0.0-SNAPSHOT.jar to spark jars directory。
cp /your_path/spark-doris-connector/target/spark-doris-connector-3.1_2.12-1.0.0-SNAPSHOT.jar  $SPARK_HOME/jars
  1. created doris database and table。

    create database mongo_doris;
    use mongo_doris;
    CREATE TABLE data_sync_test_simple
     (
             _id VARCHAR(32) DEFAULT '',
             id VARCHAR(32) DEFAULT '',
             user_name VARCHAR(32) DEFAULT '',
             member_list VARCHAR(32) DEFAULT ''
     )
     DUPLICATE KEY(_id)
     DISTRIBUTED BY HASH(_id) BUCKETS 10
     PROPERTIES("replication_num" = "1");
    INSERT INTO data_sync_test_simple VALUES ('1','1','alex','123');
    1. Input this coed in spark-shell.
import org.apache.doris.spark._
val dorisSparkRDD = sc.dorisRDD(
  tableIdentifier = Some("mongo_doris.data_sync_test"),
  cfg = Some(Map(
    "doris.fenodes" -> "127.0.0.1:8030",
    "doris.request.auth.user" -> "root",
    "doris.request.auth.password" -> ""
  ))
)
dorisSparkRDD.collect()
  • mongo_doris:doris database name
  • data_sync_test:doris table mame.
  • doris.fenodes:doris FE IP:http_port
  • doris.request.auth.user:doris user name.
  • doris.request.auth.password:doris password
  1. if Spark is Cluster model,upload Jar to HDFS,add doris-spark-connector jar HDFS URL in spark.yarn.jars.
spark.yarn.jars=hdfs:///spark-jars/doris-spark-connector-3.1.2-2.12-1.0.0.jar

Link:apache/doris#9486

  1. in pyspark,input this code in pyspark shell command.
dorisSparkDF = spark.read.format("doris")
.option("doris.table.identifier", "mongo_doris.data_sync_test")
.option("doris.fenodes", "127.0.0.1:8030")
.option("user", "root")
.option("password", "")
.load()
# show 5 lines data 
dorisSparkDF.show(5)
