Not able to access /tmp folder in HDFS

Question

I have started the name node, datanode and mr service on my local machine and all the service are running. Here is what's the result of jps command:

kv:~ karan.verma$ jps
4499 SecondaryNameNode
420 
4676 NodeManager
4741 JobHistoryServer
5125 Jps
4406 DataNode
4600 ResourceManager
4333 NameNode

And i could easy browse throw the "browse directory" of the web UI for name node. But when i try to browse the /tmp directory, it shows me the following error:

Permission denied: user=root, access=READ_EXECUTE, inode="/tmp":karan.verma:karan.verma:drwxrwx-w-

I tried to change the permissions using following command:

hadoop fs -chown -R karan.verma:karan.verma hdfs://localhost/
hadoop fs -chmod a+w /

but no luck. Please suggest what could be the issue? I executed the above commands with sudo, but still the same result. Any Help?

Answer 1

Executing the following command solved the issue for me:

hadoop fs -chmod -R 777 hdfs://localhost/

Answer 2

it looks like you are running as root and the file system to is owned by karan.verma.

you can confirm this by running

whoami

either su to karan.veram or add root to the karan.verma group
