[jira] [Resolved] (MAHOUT-1127) OnlineLogisticRegression test is flaky (and wrong)

     [ https://issues.apache.org/jira/browse/MAHOUT-1127?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ted Dunning resolved MAHOUT-1127.
---------------------------------

    Resolution: Fixed

The problem had to do with how the loop was accumulating results.

I fixed that and also made the test be deterministic by freezing the key.  Even without a fixed key, the statistical test now should fail at less than one in a very large number of trials (> 10^5) and I have a retry logic that allows a very few retries.
