Andrew Musselman created MAHOUT-2057:
----------------------------------------
Summary: Example in README results in class not found
Key: MAHOUT-2057
URL: https://issues.apache.org/jira/browse/MAHOUT-2057
Project: Mahout
Issue Type: Bug
Affects Versions: 0.14.0
Reporter: Andrew Musselman
Fix For: 0.14.1
Running the example in the README gives a class not found:
"java.lang.NoClassDefFoundError:
it/unimi/dsi/fastutil/ints/Int2DoubleOpenHashMap"
If that's just us still using something that's been removed, it's not a
deal-breaker for me as long as we fix it in a quick point release.
Pending that being a simple fix my vote is +1 binding, and if Andy's not back
from vacation and his proxy works that's +2 binding from me and Andy.
