Description

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.
