----------------------------------------
GitHub user roengram opened a pull request:
https://github.com/apache/mahout/pull/37
use exact path to clustering results instead of wild-card
Detail is available at https://issues.apache.org/jira/browse/MAHOUT-1593
Briefly speaking, kmeans-clustering example script doesn't run correctly
with Hadoop version: 2.4.0.2.1.1.0-385. The reason is that the script uses
wild-carded path for clustering result directory, which is not returning the
correct path. I replaced the wild-carded path with a simple combination of
commands that returns the exact path.
