[jira] [Commented] (MAHOUT-1590) mahout unit test failures due to
guava version conflict on hadoop 2
[ https://issues.apache.org/jira/browse/MAHOUT-1590?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14184536#comment-14184536 ]
Sabin Thomas commented on MAHOUT-1590:
--------------------------------------
I see the same issue as well
{code}
[root@node1 examples]# sh bin/cluster-reuters.sh
Please select a number to choose the corresponding clustering algorithm
1. kmeans clustering
2. fuzzykmeans clustering
3. lda clustering
4. streamingkmeans clustering
Enter your choice : 3
ok. You chose 3 and we'll use lda Clustering
creating work directory at /tmp/mahout-work-root
MAHOUT_LOCAL is set, so we don't add HADOOP_CONF_DIR to classpath.
MAHOUT_LOCAL is set, running locally

I will try the patch and recompile Mahout and see if I can get it resolved. Additionally, I am only seeing the above issue in MAHOUT_LOCAL mode.

> =====
> hadoop mapreduce V2 is using guava v11.0.2 and mahout is using guava version 16.0
> After trying different versions guava version 14.0 seems to have hadoop MR V2 compatible jars and mahout needed classes.
> The unit tests ran successfully after changing the dependency in mahout to v14.0
