  • 正常現象，如需在Master中啟動可在slave檔案中
    slaves
localhost
slave01
slave02

Master的ResourceManager未啟動

  1. 檢查yarn-site.xml
  2. 檢查mapred-site.xml

Slave的DateNode未啟動

  • 檢查yarn-site.xml
    yarn-site.xml
<property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
</property>

Name node is in safe mode

  • 退出Safe Mode
hadoop dfsadmin -safemode leave
