> As of 1.6, the driver registers with each shuffle manager via  MesosExternalShuffleClient.  Once this disconnects, the shuffle manager automatically cleans up the data associate with that driver.
> However, the connection is terminated before this happens as it's idle. Looking at a packet trace, after 120secs the shuffle manager is sending a FIN packet to the driver.   The only way to delay this is to increase spark.shuffle.io.connectionTimeout=3600s on the shuffle manager.
> I patched the MesosExternalShuffleClient (and ExternalShuffleClient) with newbie Scala skills to call the TransportContext call with closeIdleConnections "false" and this didn't help (hadn't done the network trace first).
