Datanode not running on Hadoop-2.7.3

0 votes

I am new to hadoop while after the installation and all the settings were done, when I run jps to see my daemons are running or not. I can see datanode is not running. 

When I try to run it manually with the command:

/sbin/hadoop-daemon.sh start datanode

Can anyone suggest an resolve to this?

Hey,

I solved this problem by removing hadoop directory in tmp just in terminal:

sudo rm -r /tmp/hadoop-<username>

Then format the file system and start the Name node and Data node, I hope it will work.
