> 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.
