WebHdfsException at /filebrowser/

Hi, I’ve just installed the sandbox and when I attempt to open the file browser I get a WebHdfsException. Here’s the Exception info:

Could you run on VM next command:
curl -i "http://sandbox:50070/webhdfs/v1/?op=LISTSTATUS"

[Brad LynchMember]

So mine is working now and the only thing I did since I posted is reboot the VM 2 times.

Wish I could help more with the root cause, but now I am able to upload through the file manager and the configuration checker is now succeeding.

I am also receiving this error.

I downloaded this the night of March 21, the filename is: Sandbox+HDP+Bombardier2+(14.03)+VMware.ova.

Would like to be able to upload the first tutorial file. Thank you in advance if anybody knows how to fix this.

Hi, Aaron,

I didn’t see the issue. Can you tell me the steps you see the issue? And are you using the new version of sandbox?

Larry

[Arnaud LINZMember]

Same for me. No solution ?

[Mirko CarraraMember]

Hi, I get the same error message. I think is due to a permission misconfiguration:

hadoop.hdfs_clusters.default.webhdfs_url Current value: http://localhost:50070/webhdfs/v1/
Failed to access filesystem root

I’m still checking logs to find out which could be solution.
In the meanwhile, is there anyone else who solved this error?
