Thank you so much for your tutorial. I just have some questions hope you can help:
after running start-dfs.cmd and start-yarn.cmd in cmd (boot HDFS step) I noticed that the yarn is working fine but NameNode and DataNode started for a few secs and then both stopped working for some reasons. Any idea what might cause this issue?
during the setting path process, I couldn't run the command: hdfs -version (I cd out to C:/User but I still have the same error Error: Could not find or load main class Last Name) so I edit /etc/hadoop/hadoop-env.cmd and change this line:
set HADOOP_IDENT_STRING=%USERNAME%
to
set HADOOP_IDENT_STRING=myuser
This allows me to do hdfs -version but I don't know this change will affect anything or not could you please clarify? Is this change make my NameNode and DataNode not working
