Hi. We posted a newer version of this code: https://github.com/NetApp/NetApp-Hadoop-NFS-Connector/releases/tag/v1.0.6. There is a patch for Hadoop since it has a bug.
Try that instead and see.

Hi, I got the same error as @danielhaviv

After replacing the nfs-hadoop.jar with your 3.0.0-version, the original error is gone, but there is still an error:

I'm using Cloudera CDH 5.5.2.

Do you have any ideas how to fix this problem? Mountin the nfs via usual Linux commands works like a charm.

Best regards,
Benjamin

edit: I added the nfs-mapping.json for further reference:

Hey check controller side "unix-user" and "unix-group"-

  1. root user's UserID and GroupID of your SVM should be 0 and not 1.

  2. Also create separate users.json file and group.json file.

You can refer to TR-4382 for creating these files. I guess this might help you to get rid of the problem mentioned above.

With 2.7.1 there is a open issue "https://issues.apache.org/jira/browse/HADOOP-12345". Please
try with "2.8.0, 3.0.0-alpha1".
