[jira] [Commented] (BIGTOP-255) add tests for Mahout

    [ https://issues.apache.org/jira/browse/BIGTOP-255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13148969#comment-13148969 ] 

Bruno Mahé commented on BIGTOP-255:
-----------------------------------

By looking at the diff of MAHOUT-680, wouldn't we be able to go around that issue by tweaking CLASSPATH and HADOOP_CLASSPATH in mahout wrapper?

> I have written some tests to run Mahout examples. The tests were developed against CDH3u2. However, they do not run against Mahout 0.5 which is what is in Bigtop. (CDH3u2 has Mahout 0.5+patches.)
> The tests all fail if you run against Mahout 0.5 as is. If you apply the patch for MAHOUT-680 (which simply patches /usr/lib/mahout/bin/mahout), then the tests run, but 2 tests fail.
> The tests all pass against CDH3u2, but that has java patches, notably for MAHOUT-708.
