    SPARK-1254. Supplemental fix for HTTPS on Maven Central · abf6714e
    Sean Owen authored
    It seems that HTTPS does not necessarily work on Maven Central, as it does not today at least. Back to HTTP. Both builds works from a clean repo.
    
    Author: Sean Owen <sowen@cloudera.com>
    
    Closes #209 from srowen/SPARK-1254Fix and squashes the following commits:
    
    bb7be47 [Sean Owen] Revert to HTTP for Maven Central repo, as it seems HTTPS does not necessarily work
