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');
- 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
- 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.jarLink：apache/doris#9486
- 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")
