Hello all,
I have started to play around with Mahout today. During installation,
the unit test testStartParallelFPGrowth is failing. (I am not sure whether
to send this post
here or to the developer list).
Adding the -e option to maven, we get the culprit
Failed tests:
testStartParallelFPGrowth(org.apache.mahout.fpm.pfpgrowth.PFPGrowthTest):
expected:<{[D=0, E=1, A=0, B=0, C]=1}> but was:<{[A=0, B=0, C=1, D=0, E]=1}>
Unfortunately, this is an algorithmic area in which I have no background (I
work in optimization/linear algebra) so I don't feel comfortable digging
into this myself.
I downloaded the Mahout src, version .5 this afternoon. The only small
hitch in my setup
is that I am running this under the IBM Java JDK:
$java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build pxa6460sr7-20091215_02(SR7))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux amd64-64
jvmxa6460sr7-20091214_49398 (JIT enabled, AOT enabled)
J9VM - 20091214_049398
JIT - r9_20091123_13891
GC - 20091111_AA)
JCL - 20091202_01
With Maven version 3.03
$mvn -version
mvn -version
Apache Maven 3.0.3 (r1075438; 2011-02-28 12:31:09-0500)

I should also add that I am not currently using Hadoop beneath Mahout yet, I
have not had
the time to get it running on our cluster.
I do not plan on using this functionality; however, I am more than happy to
help drill into this to
find the issue.
Thanks in advance,
marc
