Ubuntu16.04安装flink-1.10.0

本来想cdh集成flink，但是我的cdh版本为5.16.2，参考了下面的issue可能cdh版本太低，至少要cdh6

https://github.com/pkeropen/flink-parcel/issues

进行独立安装

wget https://mirrors.tuna.tsinghua.edu.cn/apache/flink/flink-1.10.0/flink-1.10.0-bin-scala_2.11.tgz

安装路径

/home/lintong/software/apache/flink-1.10.0

/etc/profile添加，并source /etc/profile

#flink
export FLINK_HOME=/home/lintong/software/apache/flink-1.10.0
export PATH=${FLINK_HOME}/bin:$PATH

下载flink-shaded-hadoop-2-uber-2.7.5-7.0.jar包，放到flink的lib目录下

wget https://repo1.maven.org/maven2/org/apache/flink/flink-shaded-hadoop-2-uber/2.7.5-7.0/flink-shaded-hadoop-2-uber-2.7.5-7.0.jar

不然flink on yarn的时候会报

启动yarn-session

yarn-session.sh -n 3 -s 5 -jm 1024 -tm 4096 -d

yarn-seesion参数

  -n ： 指定TaskManager的数量；
  -d: 以分离模式运行；
  -id：指定yarn的任务ID；
  -j:Flink jar文件的路径;
  -jm：JobManager容器的内存（默认值：MB）;
  -nl：为YARN应用程序指定YARN节点标签;
  -nm:在YARN上为应用程序设置自定义名称;
  -q:显示可用的YARN资源（内存，内核）;
  -qu:指定YARN队列;
  -s:指定TaskManager中slot的数量;
  -st:以流模式启动Flink;
  -tm:每个TaskManager容器的内存（默认值：MB）;
  -z:命名空间，用于为高可用性模式创建Zookeeper子路径;

去CDH上查看，第一个是正在运行，第二个是结束

去appliance id进到yarn的app页面

再点击ApplicationMaster进到Flink Dashboard页面

再提交Flink任务到yarn上

lintong@master:~/software/apache/flink-1.10.0$ bin/flink run examples/batch/WordCount.jar

再查看Flink Dashboard

输出

如果页面中的Available task slot一直为0的话，运行任务报，那说明yarn的资源不够

去cdh上调整yarn.nodemanager.resource.memory-mb，容器内存，我这边从2G调整成4G就可以运行flink任务
