Not able to access /tmp folder in HDFS

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?

Solution

  • Executing the following command solved the issue for me:

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