Subject Re: Cannot start Data Node and Node Manager in Hadoop 2.2.0

Please send the log. Otherwise there are couple of fix you can try. 
- Whenever data node start it connect to namenode. Check if your datanode is connecting to
NN. It might have port conflict issue.
- other very common problem is file locking problem when starting namenode. You might have
started NN before which would have made locks. So remove lock file and may be format NN.
- However refrain of formatting NN frequently.
