Allow use of random seeds during unit tests
-------------------------------------------
Key: MAHOUT-743
URL: https://issues.apache.org/jira/browse/MAHOUT-743
Project: Mahout
Issue Type: Improvement
Reporter: Lance Norskog
Attachments: RandomWrapper.patch
The RandomUtils package has a trick for running unit tests repeatably. All
random generators created with RandomUtils.getRandom() are started with seed 0.
Unfortunately, all random generators started with RandomUtils.getRandom(seed)
effectively run from a seed of 0. Thus, code which deliberately creates Random
objects with seeds does not work correctly under unit tests.
The problem is that the logic in RandomWrapper tests for unit test mode and
settable seed mode in the wrong order.
