Data Node not started

Question

I configured hadoop setting in my box and worked with example programs everything went fine and worked well all the Daemons also is in the running state. On the next day morning Data node not running.

Could you check the datanode log and post the latest lines here? Normally you can find the log under `$HADOOP_HOME/logs/`. — Pieterjan, Jan 08 '13 at 08:16
start-dfs.sh? Why do you think that data node is not running? — Yevgen Yampolskiy, Jan 10 '13 at 03:04

Try restarting the hadoop and also format the namenode . Generally the issue resolves on restarting the hadoop

I solved this problem in the following way:

1.By writing "localhost" in the file "hostname" which is located at /etc. And restart once it will work fine.

stop all services. Add hostname to conf/slaves and run start-all.sh
