flink的安装包我们前面已经下载好了，上传到集群，解压，我这里命名成flink-on-yarn
现在flink的软连接指向
我们改成指向flink-on-yarn
修改hadoop的配置文件的yarn-siite.xml
<property>
<name>yarn.resourcemanager.am-attempts</name>
<value>4</value>
</property>
把该配置文件分发给其他节点
scp -r yarn-site.xml hadoop@slave1:/opt/modules/hadoop-2.8.5/etc/hadoop/ scp -r yarn-site.xml hadoop@slave2:/opt/modules/hadoop-2.8.5/etc/hadoop/
以上参数都是默认的，我们可以不用配置

出现此类错误，主要的原因是Current usage: 75.1 MB of 1 GB physical memory used; 2.1 GB of 2.1 GB virtual memor
y used. Killing container.
字面原因是容器内存不够，实际上是flink on yarn启动时检查虚拟内存造成的
所以修改配置文件，让它不检查就没事了
修改etc/hadoop/yarn-site.xml
<property>
<name>yarn.nodemanager.vmem-check-enabled</name>
