• sqlclient启动前准备
• 启动sqlclient
• init.sql
• insert.sql

环境准备

组件名	版本
flink客户端	1.14.4-2.12
hadoop集群	3.1.4
hive客户端	3.1.2
iceberg	iceberg-flink-runtime-1.14-0.13.2.jar
iceberg-hive依赖	iceberg-hive-runtime-0.13.2.jar

sqlclient启动前准备

sqlclient启动有两种方式，per-job、session。

session模式需先启动一个session，启动方式如下：

/home/hadoop/flink/bin/yarn-session.sh \
-t /home/hadoop/flink/sqlplugins \
-s 2 -jm 5120 -tm 5120 -qu default -nm iceberg_test1 -d

per-job模式需在flink客户端的flink-conf.yaml文件中添加如下参数：
execution.target: yarn-per-job

注意：

flink-conf.yaml文件中还设置了其他内容如下
classloader.resolve-order: parent-first

classloader.check-leaked-classloader: false

#kerberos相关配置
security.kerberos.login.use-ticket-cache: true
security.kerberos.login.keytab: /bigdata/apps/test/core.keytab
security.kerberos.login.principal: hadoop
security.kerberos.login.contexts: Client

启动sqlclient

-- yarn session模式
/home/hadoop/flink/bin/sql-client.sh  embedded \
-s appId \
-l /home/hadoop/flink/sqlplugins \
-i /home/hadoop/flink/script/init.sql \
-f /home/hadoop/flink/script/insert.sql \
shell

-- yarn per-job模式
/home/hadoop/flink/bin/sql-client.sh  embedded \
-l /home/hadoop/flink/sqlplugins \
-i /home/hadoop/flink/script/init.sql \
-f /home/hadoop/flink/script/insert.sql \
shell
