    Latest Hadoop 3.2.1 Installation on Windows 10 Step by Step Guide
    
    Fix the issue only
    I've uploaded the updated JAR file into the following location. Please download it from the following link:
    
    https://github.com/FahaoTang/big-data/blob/master/hadoop-hdfs-3.2.1.jar  

    And then rename the file name hadoop-hdfs-3.2.1.jar to hadoop-hdfs-3.2.1.bk in folder %HADOOP_HOME%sharehadoophdfs.

    Copy the downloaded hadoop-hdfs-3.2.1.jar to folder %HADOOP_HOME%sharehadoophdfs.

    warning This is just a temporary fix before the official fix is published. There is no guarantee this temporary fix won't cause any new issue.
