啟動nodemanager報錯
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
主要報錯Call From slave/192.168.1.110 to 0.0.0.0:8031 failed on connection exception: java.net.ConnectException: Connection refused;
nodemanager 預設情況下，需要跟resource manager進行通訊，報告心跳資訊
通訊引數通過
yarn.resourcemanager.resource-tracker.address 進行設定
引數解釋：ResourceManager 對NodeManager暴露的地址.。NodeManager通過該地址向RM彙報心跳，領取任務等。
預設值：${yarn.resourcemanager.hostname}:8031
所以預設與 0.0.0.0:8031進行通訊
我們可以直接修改yarn.resourcemanager.resource-tracker.address
<property>
<name>yarn.resourcemanager.resource-tracker.address</name>
<value>resource manager節點IP:8031</value>
</property>或者修改yarn.resourcemanager.hostname引數
<property> <name>yarn.resourcemanager.hostname</name> <value>resource manager節點IP</value> </property>
進行定義
