Namenode not getting started

0 votes

I cannot start the namenode and datanode, earlier it was working fine, but then i had to restart the VM for some reason. 

I tried both bin/start-all.sh and bin/start-dfs.sh.

You need to delete the contents of the temporary folder, then format the namenode.

rm -Rf <tmp dir>

bin/hadoop namenode -format

bin/start-all.sh

Hope it helps
