[jira] [Created] (SPARK-12450) Un-persist broadcasted variables in KMeans

RJ Nowling created SPARK-12450:
----------------------------------

             Summary: Un-persist broadcasted variables in KMeans
                 Key: SPARK-12450
                 URL: https://issues.apache.org/jira/browse/SPARK-12450
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
    Affects Versions: 1.5.2, 1.4.1
            Reporter: RJ Nowling
            Priority: Minor


The broadcasted centers in KMeans are never un-persisted.  As a result, memory usage accumulates with usage causing a memory leak.
