Colin Patrick McCabe commented on HTRACE-144:
---------------------------------------------
Also as I wrote above, with version 3 and 4 of the patch, you can now set your
process id to {{$\{ip}.$\{pid}} }, to uniquely identify multiple daemons on the
same host.
> Include IP address in span process description

> Right now, we have no IP address or hostname specified in the span process
> description. So if we have 100 datanodes, the spans from all of them simply
> show up as "DataNode." Obviously this is unsatisfactory.
