Если бы oop nodemanager не запускался

Я настраиваю кластер с одним узлом. Я следую руководству https://dev.to/awwsmm/installing-and-running-hadoop-and-spark-on-ubuntu-18-393h. Однако мой nodemanager не запускается.

Вот мой yarn-site. xml: 

<?xml version="1.0"?>


<configuration>

<!-- Site specific YARN configuration properties -->

  <property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
  </property>
  <property>
    <name>yarn.nodemanager.auxservices.mapreduce.shuffle.class</name>  
    <value>org.apache.hadoop.mapred.ShuffleHandler</value>
  </property>
</configuration>

Я видел много сообщений, в которых mapreduce.shuffle нужно заменить на mapreduce_shuffle. Однако на моем yarn-site. xml у меня уже есть mapreduce_shuffle.

  1. из журналов mapreduce_shuffle , я заметил, что после значения mapreduce_shuffle добавляются два пробела. не могли бы вы правильно набрать и скопировать в yarn-site. xml вместо того, чтобы напрямую копировать его из блогов. это может быть связано с некоторыми специальными символами, добавленными в mapreduce_shuffle строка
  2. замените yarn.nodemanager.auxservices.mapreduce.shuffle.class тегом yarn.nodemanager.aux-services.mapreduce_shuffle.class и запустите has oop, это должно работать.
