Nodemanager 自动关闭，报错Connection refused

启动nodemanager报错

INFO org.apache.hadoop.service.AbstractService: Service NodeManager failed in state STARTED; cause: org.apache.hadoop.yarn.exceptions.YarnRuntimeException: java.net.ConnectException: Call From slave/192.168.1.110 to 0.0.0.0:8031 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused
org.apache.hadoop.yarn.exceptions.YarnRuntimeException: java.net.ConnectException: Call From slave/192.168.1.110 to 0.0.0.0:8031 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused

主要报错Call From slave/192.168.1.110 to 0.0.0.0:8031 failed on connection exception: java.net.ConnectException: Connection refused; 

nodemanager 默认情况下，需要跟resource manager进行通信，报告心跳信息

通信参数通过

yarn.resourcemanager.resource-tracker.address 进行设定
参数解释：ResourceManager 对NodeManager暴露的地址.。NodeManager通过该地址向RM汇报心跳，领取任务等。
默认值：${yarn.resourcemanager.hostname}:8031

所以默认与 0.0.0.0:8031进行通信

我们可以直接修改yarn.resourcemanager.resource-tracker.address 

    <property>
      <name>yarn.resourcemanager.resource-tracker.address</name>
      <value>resource manager节点IP:8031</value>
    </property>

或者修改yarn.resourcemanager.hostname参数

    <property>
      <name>yarn.resourcemanager.hostname</name>
      <value>resource manager节点IP</value>
    </property>

进行定义
