Nick Dimiduk commented on HDFS-8213:
------------------------------------

Hit post too soon...

What that doesn't clarify to me is how I would connect the dots of spans 
initiated within the HDFSClient back to actions takes by said app.

> DFSClient should use hdfs.client.htrace HTrace configuration prefix rather 
> than hadoop.htrace

> 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.
