Error while starting hadoop daemons

Question

I am new to hadoop as well as ubuntu and trying to install Hadoop 2.2.0 in (Ubuntu) on my system. When I tried to start the daemons using start-all.sh or start-dfs.sh, it throws an error saying "Command not found". I have issued this command as an user created under the hadoop group only.

> hduser@nitk-OptiPlex-9010:~/hadoop-2.2.0/sbin$ start-all.sh
> start-all.sh: command not found

Can someone please help me out to resolve this issue?

Also when I tried modifying the core-site, hdfs-site xml files under etc/hadoop folder, core-site.xml~, hdfs-site.xml~ files were created (New files with a tilde symbol at the end of their names got created). I deleted those new files created. Is this creating a problem?

Solution 1

Follow below steps
      ==> Go to hadoop home directory: cd /usr/local/hadoop/
      ==> Start the process of datanodes and namenodes : bin/hadoop namenode -format
==> Start deamons : sbin/start-dfs.sh (start-all.sh is depreciated)

Hope that helps you :)

Solution 2

write ./start-all.sh

If it says start-all.sh: command not found

That means its not yet into executable mode. Change it to executable via chmod

chmod +x *.sh
