Permission denied error during NameNode start

Today I observed that the NameNode was in red. I tried to restart the server, but I found the following errors. As per the suggestions mentioned in various threads, I formatted the NameNode, by using the command "hadoop namenode -format". I was logged in as 'root', when I did it. When I saw this error, I reformatted the namenode as 'hdfs' user, but I still see the followign errors. Can anyone help me understand what is going wrong.

2016-03-17 17:27:02,305 WARN namenode.FSNamesystem (FSNamesystem.java:loadFromDisk(683)) - Encountered exception loading fsimage java.io.FileNotFoundException: /hadoop/hdfs/namenode/current/VERSION (Permission denied)

Can you have a look into that folder? You specified the namenode directory to /hadoop so it either doesn't exist or you don't have access to it or it got corrupted.

Also formatting the namenode is dangerous since it also deletes all files in the cluster. Jobs may not work anymore because the libraries are missing etc. ( You can find what to setup in the manual HDP installation guide )

Ok. I have fixed this issue. I had to change the owner of the folder /hadoop/hdfs/namenode/ to hdfs user and hdfs group. I executed the following and everything is back to normal.

chown -R hdfs:hdfs /hadoop/hdfs/namenode
