Whenever I restart my ubuntu system (Vbox) and start my Hadoop, my name node is not working.

To resolve this I have to always the folders of namenode and datanode and format Hadoop every time I restart my system.

Since 2 days am trying to resolve the issue but its not working. I tried to give the permissions 777 again to the namenode and datanode folders, also I tried changing the paths for the same.

My error is

org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /blade/Downloads/Hadoop/data/datanode is in an inconsistent state: storage directory does not exist or is not accessible

Please help me to resolve the issue.

You cannot just shutdown the VM. You need to cleanly stop the datanode and namenode processes in that order, otherwise there's a potential for a corrupted HDFS, causing you to need to reformat, assuming that you don't have a backup system

I'd also suggest putting Hadoop data for a VM in its own VM drive and mount, not a shared host folder under Downloads
