错误Hadoop : secureMain datanode.DataNode配置中出现异常

Question

我正在Windows上尝试con config hadoop，我遇到了这个错误：

org.apache.hadoop.util.DiskChecker$DiskErrorException: Too many failed volumes - current valid volumes: 0, volumes configured: 1, volumes failed: 1, volume failures tolerated: 0
        at org.apache.hadoop.hdfs.server.datanode.checker.StorageLocationChecker.check(StorageLocationChecker.java:233)

2021-10-12 11:07:43,641 INFO datanode.DataNode: SHUTDOWN_MSG:

我已经尝试设置了：

<property>
    <name>dfs.datanode.failed.volumes.tolerated</name>
    <value>0</value>
  </property>

但是，我抛出了其他错误，不工作。

我只在hadoop-env.sh中设置了这个：

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export HADOOP_CLASSPATH=/usr/lib/jvm/java-8-openjdk-amd64/lib/tools.jar
