Subject Re: HDFS NFS gateway - export only a specific directory
Date Tue, 02 Jun 2015 17:20:02 GMT
Hello Ruslan,

Issues HDFS-5469 and HDFS-6056 implemented the nfs.export.point configuration property to
control the export.

https://issues.apache.org/jira/browse/HDFS-5469

https://issues.apache.org/jira/browse/HDFS-6056

Does this look like what you need?

I don't see the property in our documentation.  If you can confirm that this is what you were
looking for, then I'll enter a follow-up jira to make sure this information gets into our
documentation.

I hope this helps.

Subject: HDFS NFS gateway - export only a specific directory

Hello,

HDFS NFS Gateway by default exports / (root, whole HDFS)

Could not find a way to export just a subdirectory within HDFS.

Looked at
https://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-hdfs/HdfsNfsGateway.html
and at
http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/admin_hdfs_nfsgateway.html


$ showmount -e <nfs_server_ip_address>

You should see output similar to the following:

Exports list on <nfs_server_ip_address>:
/ (everyone)

Any ideas if this is possible to export through NFS gwateway a specific HDFS directory?


Best regards,
Ruslan Dautkhanov
