Iceberg从入门到精通系列之六：Flink集成Iceberg

一、下载Flink

下载Flink：

• https://www.apache.org/dyn/closer.lua/flink/flink-1.17.1/flink-1.17.1-bin-scala_2.12.tgz

二、解压Flink 安装包

tar -zxvf flink-1.17.1-bin-scala_2.12.tgz -C /moudle/

三、配置环境变量

vim /etc/profile.d/flink_env.sh

export HADOOP_HOME=/opt/module/hadoop-3.1.3
export PATH=$PATH:$HADOOP_HOME/bin
export PATH=$PATH:$HADOOP_HOME/sbin
#Flink 需要
export FLINK_HOME=/module/flink-1.17.1
export HADOOP_CLASSPATH = `hadoop classpath`
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop

四、激活环境变量

source /etc/profile.d/flink_env.sh

五、下载Iceberg flink jar包

下载Iceberg flink jar包：iceberg-flink-runtime-1.17-1.3.0.jar

• https://iceberg.apache.org/releases/

六、部署Iceberg flink jar包

cp iceberg-flink-runtime-1.17-1.3.0.jar /module/flink-1.17.1/lib/

七、修改flink配置

修改配置文件flink-conf.yaml

classloader.check-leaked-classloader: false
taskmanager.numberOfTaskSlots: 4

state.backed: rocksdb
execution.checkpointing.interval: 30000
state.checkpoints.dir: hdfs://hadoop1:8020/ckps
state.backed.incremental: true

local模式

修改workers

vim /module/flink-1.17.1/conf/workers

localhost
localhost
localhost

八、启动flink

bin/start-cluster.sh

九、启动flink sql client

bin/sql-client.sh embedded

至此FLink成功集成Iceberg
