> DFSClient initializing SpanReceivers is a problem for Accumulo, which manages SpanReceivers
through its own configuration.  This results in the same receivers being registered multiple
times and spans being delivered more than once.  The documentation says SpanReceiverHost.getInstance
should be issued once per process, so there is no expectation that DFSClient should do this.
