The pure java implementation of NFS server version 3, 4.0 and 4.1 including pNFS extensionwith nfs4.1-files and flex-files layout types.
To build nfs4j from source code Java11 and Maven3 are required.
To run benchmarks:
mvn verify -Pbenchmark

ThoughNFS4J is used by thedCache and other projects in production,the public API is stillunstable and subject to change (indicated by leading zero in theversion number). Thus, should be considered asbeta.
Please consult theAPI changes document when switching between version numbers.The patch level releases are not affected by API changes, of course.
licensed underLGPLv2 (or later)
NFS4J uses the linux kernel model where git is not only source repository,but also the way to track contributions and copyrights.
Each submitted patch must have a "Signed-off-by" line. Patches withoutthis line will not be accepted.
The sign-off is a simple line at the end of the explanation for thepatch, which certifies that you wrote it or otherwise have the right topass it on as an open-source patch. The rules are pretty simple: if youcan certify the below:
Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved.
then you just add a line saying ( git commit -s )
