问题
I followed this tutorial for installation of Hadoop. Unfortunately, when I run the start-all.sh script - The following error was printed on console:
hduser@dennis-HP:/usr/local/hadoop/sbin$ start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
hadoop config script is run...
hdfs script is run...
Config parameter :

And when I executed the JPS command, the following error was thrown
hduser@dennis-HP:/usr/local/hadoop/sbin$ jps
3802 Jps
I am new to hadoop so please point me to an article that will help me to install hadoop without issues
Or if possible (and more preferable) to resolve the issue faced, please let me know what went wrong and how to fix it?
回答1:
Your current user has limited permissions to /usr/local/hadoop. Try changing permissions.
sudo chmod 777 -R /usr/local/hadoop/
回答2:
Please check permission are properly set on the folder using commands chmod or chown.
Hadoop provides individual nodes to start and stop services viz., Hadoop-daemon.sh start [Node]
Similarly there are scripts to start/stop yarn. Below post has step by stem details Install Apache Hadoop http://www.hadoopstrata.com/staticpost?postNbr=7
回答3:
Check /usr/local/hadoop/logs
permissions . If it is not under hduser change the ownership.
sudo chown -R username:group directory
回答4:
Quite honestly I do not know why I got that error.. but I removed my entire installation using the instructions provided in askUbuntu and re-installed it by using the installation method described in the official site - HERE
But you were right @Krishna, the logs were created automatically after installation. My guess is that the installation that I used earlier had configuration details that were outdated and in all likeliness messed with the installation of Hadoop
回答5:
have you tried start-dfs.sh
try the following commands and see whats the response
hdfs namenode -format
start-dfs.sh
start-yarn.sh
