flink on yarn启动失败

 

我启动hadoop on yarn 集群后

[root@node1 flink-1.6.1]# ./bin/yarn-session.sh -n 2 -jm 1024 -tm 1024

报的如下错误

在其中找到

Diagnostics: Container [pid=9658,containerID=container_1570641261952_0002_01_000001] is running beyond virtual memory limits. Current usage: 91.7 MB of 1 GB physical memory used; 2.1 GB of 2.1 GB virtual memory used.

 

 

 

显然就是设置的内存超过了限制，

 

方法一：需要改小相应内存，或者增大虚拟机内存。

 

但是若flink内存设置过小又会报错

Caused by: org.apache.flink.util.FlinkException: Cannot fulfill the minimum memory requirements with the provided cluster specification. Please increase the memory of the cluster

 

这个就要依据大家自己的情况具体设置了

我经过几次尝试后设置为

[root@node1 flink-1.6.1]# ./bin/yarn-session.sh -n 2 -jm 900 -tm 900

 

方法二（推荐）：

修改各个节点的etc/hadoop/yarn-site.xml

<property>       <name>yarn.nodemanager.vmem-check-enabled</name>       <value>false</value>   </property>  

 

 

 

启动成功
