The profile in core/pom.xml is called hadoop-0.23, and does not seem to work. I tried to replace <hadoop.version> 1.0.3 </hadoop-version> in the main pom, with 0.23.4 but it seems that the central repository does not contain this jar, and I'm not able to find it on the Web :P I tried the version 0.22.0-SNAPSHOT from asf repository [1], but I got compilation errors [2]. > I wouldn't recommend you use 0.23.x but that's how you would try to. Unfortunately I can't downgrade/upgrade the hadoop version on the cluster :) Thanks for your help [1] https://repository.apache.org/content/repositories/public/org/apache/hadoop/hadoop-core/ [2] http://pastebin.com/8vVJDVQW > On Mon, Oct 29, 2012 at 7:06 PM, Diego Ceccarelli < > [email protected]> wrote: >> Hi Sean, >> I took a look to the profiles and in core there is this 'hadoop-0.23' but >> if I >> try to compile: >> >> mvn -P hadoop-0.23 install -DskipTests >> >> Maven returns with this weird error: >> >> [ERROR] Failed to execute goal on project mahout-core: Could not >> resolve dependencies for project >> org.apache.mahout:mahout-core:jar:0.8-SNAPSHOT: The following >> artifacts could not be resolved: >> org.apache.hadoop:hadoop-common:jar:1.0.4, >> org.apache.hadoop:hadoop-mapreduce-client-common:jar:1.0.4, >> org.apache.hadoop:hadoop-mapreduce-client-core:jar:1.0.4: Failure to >> find org.apache.hadoop:hadoop-common:jar:1.0.4 in >> http://repo1.maven.org/maven2 was cached in the local repository, >> resolution will not be reattempted until the update interval of >> central has elapsed or updates are forced -> [Help 1] >> >> (seems that it is looking for the wrong version of hadoop..) >> I also tried to replace the property hadoop.version in the main pom, >> but it seems that there is not >> hadoop 0.23* in maven central, and I'm not able to find a the a jar to >> install it in my local repo :(( >> At the end I tried with 0.20.2, and I was able to compile but I got >> the same previous error >> when I launched mahout :P >> >> -- Computers are useless.
