编译 Flink

1. 创建服务目录

mkdir -p /data/flink

2. 下载介质

wget https://archive.apache.org/dist/flink/flink-shaded-10.0/flink-shaded-10.0-src.tgz -P /data/flink
wget https://archive.apache.org/dist/flink/flink-1.10.2/flink-1.10.2-bin-scala_2.12.tgz -P /data/flink

3. 编译 Flink Shaded

# 解压 Flink Shaded 压缩包
tar -xzf /data/flink/flink-shaded-10.0-src.tgz -C /data/flink

# 备份初始配置文件
cp /data/flink/flink-shaded-10.0/pom.xml /data/flink/flink-shaded-10.0/pom.xml.orig

# 修改配置文件
# 在 170 行的 "" 前，添加如下配置

# 编译 Flink Shaded
# - clean: 在构建项目之前,清理先前生成的文件。它会删除 target 目录
# - install: 将构建的项目文件安装到本地 Maven 仓库中。其他项目可以从本地仓库中引用这个项目
# - DskipTests: 在构建期间跳过运行测试
# - Pvendor-repos: 激活 Maven profile 为 vendor-repos
# - Dhadoop.version=3.0.0-cdh6.3.2: 指定 Hadoop 版本为 3.0.0-cdh6.3.2 
# - Dscala-2.12: 指定 Scala 版本为 2.12
# - Drat.skip=true: 跳过 "Release Audit Tool"（RAT）检查。RAT 用于检查项目是否符合 Apache 许可证要求
# - T10C: 启用并行构建，线程数为 10，C 表示以类的方式执行构建
cd /data/flink/flink-shaded-10.0/ && mvn clean install -DskipTests -Pvendor-repos -Dhadoop.version=3.0.0-cdh6.3.2 -Dscala-2.12 -Drat.skip=true -T10C

配置 Flink Parcel

1. 节点配置

# 将 csd 文件存入 cloudera-scm-server 节点的 /opt/cloudera/csd 目录下
scp FLINK-1.10.2.jar FLINK_ON_YARN-1.10.2.jar root@cloudera-scm-server:/opt/cloudera/csd

# 配置 Httpd 服务，外发 Flink Parcel 配置及介质
ln -s /data/flink/flink-parcel/FLINK-1.10.2-BIN-SCALA_2.12_build /var/www/html/flink1.10.2

# 查看外发 Flink Parcel 配置及介质
ll /var/www/html/flink1.10.2/
-rw-r--r-- 1 root root 280629521 Nov 27 15:47 FLINK-1.10.2-BIN-SCALA_2.12-el7.parcel
-rw-r--r-- 1 root root        41 Nov 27 15:47 FLINK-1.10.2-BIN-SCALA_2.12-el7.parcel.sha
-rw-r--r-- 1 root root       583 Nov 27 15:47 manifest.json

# 备份原文件
cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.orig

# 调整配置文件
# 将 284 行更改为如下配置
AddType application/x-gzip .gz .tgz .parcel

# 重启服务使其生效
systemctl restart httpd

# 查看外发状态
curl http://${httpd_server_ip}/flink1.10.

2. CM Web UI，选择 Parcel 配置，添加 http://${httpd_server_ip}/flink1.10.2

3. Parcel 中将会识别 Flink Parcel 包

4. 下载 => 分配 => 激活 Parcel 包

部署 Flink 服务

1. 重启 cloudera-scm-server 服务

systemctl restart cloudera-scm-server

2. 将 Flink Shaded 存入指定路径

# 所有 cloudera-scm-agent 都需进行如下操作
cp /data/flink/flink-shaded-10.0/flink-shaded-hadoop-2-parent/flink-shaded-hadoop-2-uber/target/flink-shaded-hadoop-2-uber-3.0.0-cdh6.3.2-10.0.jar /opt/cloudera/parcels/FLINK/lib/flink/lib/

3. 按流程完成 Flink 部署（若未配置 kerberos，需将两项 kerberos 配置清空）

验证 Flink 服务

1. 查看 YARN 应用程序，存在驻留任务 “Flink session cluster”

2. 通过此任务信息，跳转至 Flink Dashbord
