Brandon Li updated HDFS-4750:
-----------------------------
Attachment: nfs-trunk.patch
Uploaded the patch.
Before split it into a few JIRAs, I now temporarily put the nfs implementation
only under hdfs to make one patch. The test classes are not included.
Some subsequent JIRAs will be filed later to address security, stability and
other issues.
To do some tests with current code: make sure to stop nfs service provided by
the platform, keep rpcbind(or portmap) running,
1. start hdfs
2. start nfs gateway using "hadoop nfs3". The nfs gateway has both mountd and
nfsd. It has one export HDFS root "/" rw to everyone.
3. mount export to the client, using option such as "-o
soft,vers=3,proto=tcp,nolock". Make sure the users on client and server hosts
are in synce since nfs gateway uses AUTH_SYS authentication.
> Support NFSv3 interface to HDFS

> Key: HDFS-4750
> URL: https://issues.apache.org/jira/browse/HDFS-4750
> Project: Hadoop HDFS
> Issue Type: New Feature
> Affects Versions: 3.0.0
> Reporter: Brandon Li
> Assignee: Brandon Li
> Attachments: HADOOP-NFS-Proposal.pdf, nfs-trunk.patch

>
> Access HDFS is usually done through HDFS Client or webHDFS. Lack of seamless
> integration with client’s file system makes it difficult for users and
> impossible for some applications to access HDFS. NFS interface support is one
> way for HDFS to have such easy integration.
> This JIRA is to track the NFS protocol support for accessing HDFS. With HDFS
> client, webHDFS and the NFS interface, HDFS will be easier to access and be
> able support more applications and use cases.
> We will upload the design document and the initial implementation.
