the problem of importing org.apache.mahout.common.FileLineIterable
Dear All,
I am trying to compile the examples in "Mahout in Action". For chapter 05,
there is a program named as "GenderRescorer.java". It includes the following
class as following:
import org.apache.mahout.common.FileLineIterable;
However, the Eclipse gives the following error message:
The import org.apache.mahout.common.FileLineIterable cannot be resolved
I have included mahout-core library in the path. What is the reason cause
the above issue and how to fix it?

I don't use Eclipse, I use IntelliJ Idea (Thanks Ted) so I can only tell you
my experience for this particular IDE but it should give you an approach to
follow for Eclipse too.
In Idea, one has to import the Mahout jar files as dependencies into the
application. Provided that Mahout is installed properly, the jars which you
need are located under the core/target/ directory. These jars contain all
packages, including the one which you need.

Based on the API documentation, it seems that this FileLineIterable belongs
to
package org.apache.mahout.common.iterator
But how can I ensure to import this specific package, and where to download
it at first?
I already included mahout-core in the build path. Shouldn't that includes
this specific package? Thanks.

import org.apache.mahout.common.iterator.FileLineIterable;
In general, you should consult the API documentation of Mahout for the
correct packages to import.

For debugging, you can probably hunt it down pretty quick in the source. perhaps package name needs "iterator" in the example code?
cheers.

Yes, 0.5 is the latest stable release.
However, it is recommended that you use the trunk build as instructed on:
https://cwiki.apache.org/confluence/display/MAHOUT/BuildingMahout
The API documentation link given on Mahout's website reflects the latest
trunk build as well.

It has since moved to package
org.apache.mahout.common.iterator.FileLineIterable.
The final version fo the book would reflect changes like this.
