Thank you soo much brother...your way of teaching is soo amazing and easy, anyone can understand. I wish I had a teacher like you in my school.
Thanks a ton Gowtham, the video is really helpful.! Now that we know how to start, I just Googled on how to stop the dfs and yarn daemons :)
2 years ku munadiye itha pathilam sollirukiye bro ! Nanga ippothan intha first step eh varom ! What is datascience in tamil nu 😂 Neenga ippo enna bro pandringa ! Very excited to know about you ! 🙂❤❤
Great explanation!
latest Hadoop version got worked file instead of Slaves file (helpful tip while setup of Hadoop in Linux)
Can i download the latest version of hadoop ie 3.3.3 , which is available as of now?
Hi Gowtam, really useful and you are doing great job. After installation It is not showing Resource Manager for me.
Kindly please check the pinned comment , for few people they have to follow one step which I missed to mention in the video , in the pinned comment I have mentioned it
if you are facing problem with the adding the path to .bashrc the try to install vim.
and if the hadoop dosen't get formatted try to change the username
eg: export JAVA_HOME=/home/username/jdk1.8.0_ 45 --> export JAVA_HOME=/home/test/jdk1.8.0_ 45
For people datanode not working and not show in jps, maybe your namenode and datanode cluster ID does not match.
Follow these steps:(with config in video)
1.Delete folder hadoop2_dir
2. cd hadoop-2.9.1
3. bin/hadoop namenode -format
4. sbin/start-all.sh
Thank you. I was having that issue
Thank you
Hi Gowtham thanks for the great content, My resource manager and node manager both are not starting even after changing to localhost:8032. and I've configured every file correctly. Or else can you provide any iso with complete configurations.
Great Job! Thank you so much for this video :)
Thanks a lot mann😍😍
its good to start one by one.
Hi Gowtham, my installation is completed, i can see the jps, datanode,namenode and Secondarynamenode getting printed when i run .../hadoop-3.4.0 jps command but the localhost:8088 page is not loading, please assist
Hi Gowtham, which video I should go through after this video. Can you specify the order to watch
Will it be able to run spark-shell - -master yarn command?
HI, WHEN I GIVE JPS COMMAND , RESOURCE MANAGER IS NOT SHOWING , WHAT SHOULD BE DONE?
If the Resource Manger daemon is not started, please go to yarn-site.xml file and replace {yarn.resourcemanager.hostname}:8032 to localhost:8032 , now start the Hadoop

sudo apt install openjdk-11-jdk-headless
i have installed with above command still again shows same can you please let me know how to do that
Please do video on how to install multiple nodes
i installed this on my ubuntu server and access the webUI in my local but cant to do upload or mkdir. im using hdfscli module in python too but it return error when writing file to hdfs. do you know why?
Hello. Thanks for the video tutorial. I had Hadoop working previously some weeks ago. After upgrading Mac OS to Monterey, it doesn't seem to want to open the web UI page. "./start-all.sh" did execute but with some errors. "Unable to load native-hadoop library for your platform... using builtin-java classes where applicable" was what I got when initiating secondary namenode. I reinstalled Java but nothing changed. Running jps showed results below:
16768 DataNode
17266 Jps
16904 SecondaryNameNode
What can I do?
Have you uploaded the video of Hive , Spark installation ?
hey how to do hadoop setup on server, what are initial requirements for that ? can you please help me ?
i am getting error like>>> /usr/bin/env: ‘bash’: No such file or directory
while i am typing bin/hadoop namenode -format can youy please help me ?
When doing format we have only created namenode dir. Will the datanode dir created while starting hadoop ?
unknowingly I executed format command .Now metadata in name node is deleted and HDFS is not starting. What should I do now bro?
Please do the following
1. Stop running Hadoop Deamons
2. Delete the directory hadoop2-dir from home folder
3. Then again run the name node format command
4. Finally start Hadoop daemons
That's it 🙂

Sir am to able to write after fi in terminal @6:44
no slave file in 3.0 version
Unable to start node manager and resource manager. Automatically shutting Down. Please help
If the Resource Manger daemon is not started, please go to yarn-site.xml file and replace {yarn.resourcemanager.hostname}:8032 to localhost:8032 , now start the Hadoop
@@dataengineeringvideos Hi, updated the file. Even then I cannot see Resource Manager and Node Manager after running jps command. While starting the hadoop, it shows that it is starting Resource Manager and Node Manager. But after starting, when I enter jps command, I do not see any of the 2 in the list. What can be done? Please help.
just one suggestion, u will be saying everything i will be putting in description box but not a single thing will be there
May i know what information is missing ?
Hello Sir, I have started Hadoop with all those steps what you mentioned but only 3 Daemon process are running well except NodeManager and Resource manager, please provide solution, thanks in advance.
Hey Hi, I am facing the same issue. Please provide the solution
If the Resource Manger daemon is not started, please go to yarn-site.xml file and replace {yarn.resourcemanager.hostname}:8032 to localhost:8032 , now start the Hadoop

I am facing same issue please let me know if you have fixed it
ERROR: /home/archita/jdk-8u351-linux-x64/bin/java is not executable . I am getting this error everytime. How to resolve this?
i am getting error like>>>
/home/adwait/hadoop-2.9.2/bin/hdfs: line 319: /home/adwait/jdk-8u202-linux-x64/bin/java: No such file or directory
while i am typing bin/hadoop namenode -format could you please give its solution
Got it! I was making a very silly mistake, while setting the path variable i was setting it as /home/test/jdk_802 while the correct one was one directory lower than this since I got another folder while extracting the tar.gz file. So it solved after setting it as /home/test/jdk_802/jdk_1.8.0_22
Bro unga number contact pannanum bro rosirce node work agala
Are these steps same for windows
~/hadoop-2.9.1$ bin/hadoop namenood -format
Error: Could not find or load main class namenood
Caused by: java.lang.ClassNotFoundException: namenood
how can i solve this problem
