> The HdfsProducer uses an instance variable (long splitNum) that is incremented to create unique output filenames in a given directory (seg0, seg1, etc).  
> If the Producer instance is recreated (producer cache limit exceeded, server restart, etc), the splitNum variable is reset to 0.  This results in files being overwritten when using overwrite=true mode or throwing "The file already exists" errors when using overwrite=false mode.
> We should switch to using a timestamp or some other unique generator to prevent filename collisions regardless of the Producer instance lifecycle for the same hdfs directory URL...
