This is a map reduce code of calculating pi value "hadoop jar /home/rakib/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.2.4.jar pi 10 100". You can watch Hive installation video for more use cases of Map Reduce.
Ejecute jps en la línea de comando y verifique que todos los nodos funcionen correctamente o no. Si funciona, utilice localhost:50070 para conectar hadoop desde el navegador.
delete namenode and datanode folders under /home/user/hadoop/data using rm -r command, again create those folders in that location after that format the namenode finally start the hadoop cluster
may be some properties need to be added in mapred-site.xml file. So when you run the any hdfs command it'll show error and show some properties needed to be updated, copy those properties into mapred-site.xml file with hadoop_home path.

Thank you for this great video. However, only the last step did not work with me "Unable to connect". what could be the problem?
First uninstall SSH, then follow configure the SSH section on the video after that install SSH.
THANKS I LOVE YOU 😭😭😭

is it possible to install hadoop on different disk? I tried to do the same on path: /media/ubuntu/D/hadoop/etc/hadoop and it didn't work
Yes, it's possible. You have to give the access permission of that path using chmod
Thaaaank you a looooot ❤
thanks a lot
You are most welcome
🙏👏
Inside hadoop lib folder is not present
Go inside Hadoop folder using cd command then press ls. You can see lib folder is present.
how to create hadoop_install_config.txt file. I have no this file in my downloads
you can find that file in video description.
Hola hice todo el procedimiento pero cuando me voy a conectar desde el navegador no me lo permite
Ejecute jps en la línea de comando y verifique que todos los nodos funcionen correctamente o no. Si funciona, utilice localhost:50070 para conectar hadoop desde el navegador.
What's the song or the instrument in the intro?
thanks bro
Welcome
My datanode is not showing. When I ran jps command
delete namenode and datanode folders under /home/user/hadoop/data using rm -r command, again create those folders in that location after that format the namenode finally start the hadoop cluster
Why the name node is not showing.
check web UI after starting the nodes using this link localhost:9870/
Why it can not run command hdfs?
may be some properties need to be added in mapred-site.xml file. So when you run the any hdfs command it'll show error and show some properties needed to be updated, copy those properties into mapred-site.xml file with hadoop_home path.
asegúrate de que estés en la ruta /home/tu_usuario/hadoop/bin/, me pasó lo mismo, y luego ejecutas : hdfs namenode -format
Localhost: permission denied (publickey,password). how can i fix this?
