Hadoop namenode formatting windows - java.lang.UnsupportedOperationException

java windows hadoop windows-10 hadoop3

It is well known apparently that hadoop 3.2.1 doesn't work on windows 10 properly. I installed 3.2.0 and am now making progress.

java windows hadoop windows-10 hadoop3

The following error is a Bug in Hadoop 3.2.1.

This issue will be solved within the next release. For now, you can fix it temporarily using the following steps:

Download hadoop-hdfs-3.2.1.jar file from the following link.
Rename the file name hadoop-hdfs-3.2.1.jar to hadoop-hdfs-3.2.1.bak in folder %HADOOP_HOME%\share\hadoop\hdfs
Copy the downloaded hadoop-hdfs-3.2.1.jar to folder %HADOOP_HOME%\share\hadoop\hdfs
