Hi,

Check your dfs.name.dir and dfs.data.dir path in hdfs-site.xml.

Or what can you do is: stop all the running Hadoop process and start again:

./stop-all.sh

./start-all.sh

If the error exists even after the above step, then stop all the process, format the NameNode and start again.

./stop-all.sh/

hadoop namenode -format

./start-all.sh
