version for apache nutch giraph integration and irc

[Michael Aro <m....@gmail.com>]

Hi All,

I have being reading the nutch wiki. Currently, there are branches for 2.x
e.g. 2.1 and 1.x e.g. 1.6. The trunk is the 1.6 version.

The trunk contains the ".webgraph" package including classes LinkRank.java
and WebGraph.java. These classes do not exist in Nutch 2.1. Have they being
modified in Nutch 2.1 using different names or they do not exist at all?

Is the Giraph implementation meant for 2.x, 1.x or both?

Besides, will the implementation in Giraph include the WebGraph class in
addition to the LinkRank (PageRank implementation) class? Will it just
include the implementation of all the classes in WebGraph package of
version 1.6?

Is there any irc channel for Nutch or Giraph? I can't find any on the
pages.

Trunk is for the 1.x releases (last release is 1.6),
while branches/2.x is 2.1, etc.

Webgraph hasn't been ported to 2.x yet, see NUTCH-875.

I would say that depends mainly on you.
But it may be easier to start with 1.x because
there is already a "reference" implementation.

AFIK, there is none for Nutch, only the mailing lists.

Great! I think you should get in touch with Lewis, he's the expert
on this issue.
