Hadoop NFS
|
||||
|
||||
Hadoop NFS is a Java library for building NFS gateway. It has
|
||||
the following components:
|
||||
|
||||
- ONCRPC: This a implementation of ONCRPC(RFC-5531) and XDR(RFC-4506).
|
||||
- Mount: This an interface implementation of MOUNT protocol (RFC-1813).
|
||||
- Portmap: This is a implementation of Binding protocol(RFC-1833).
|
||||
- NFSv3: This is an interface implementation of NFSv3 protocol(RFC-1813).

* defined as a sequence of n (numbered 0 through n-1) arbitrary bytes
|

* to be the number n encoded as an unsigned integer (as described
|

* below), and followed by the n bytes of the sequence.
|
||||
*
|
||||
* Byte m of the sequence always precedes byte m+1 of the sequence, and
|
||||
* byte 0 of the sequence always follows the sequence's length (count).
|
||||
* If n is not a multiple of four, then the n bytes are followed by
|
||||
* enough (0 to 3) residual zero bytes, r, to make the total byte count
|

* a multiple of four. Variable-length opaque data is declared in the
|

* following way:

*
|
||||
* opaque identifier<m>;

* or
|

* opaque identifier<>;
|

*
|

* declaration, it is assumed to be (2**32) - 1, the maximum length.
