amoners commented on HDFS-4750:
-------------------------------
"
By default, the DFSClient inside NFS gateway doesn’t flush data after each
write, and thus the user may not
be able to read back the written data immediately. The solution is to read the
data from the buffer in NFS
gateway instead of DataNode.
"
Is there any improvement in this filed? If so, could you give me a link?
Thanks,

> Support NFSv3 interface to HDFS

> Key: HDFS-4750
> URL: https://issues.apache.org/jira/browse/HDFS-4750
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: nfs
> Affects Versions: 3.0.0-alpha1
> Reporter: Brandon Li
> Assignee: Brandon Li
> Attachments: HADOOP-NFS-Proposal.pdf, HDFS-4750.patch, 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.
