> HTrace 3.2.0-incubating is coming out soon and there are some significant differences in its API.  Ideally we would like Accumulo to work with either version.  Differences include:
> * no Trace.setProcessId method
> * process ID is handled differently now; it defaults to name/IP, while before Accumulo tracked IP manually
> * SpanReceivers are expected to set process ID if it is not provided
> * return type of Span.getKVAnnotations changed from Map<byte[],byte[]> to Map<String,String>
> * Spans can now have multiple parents (although none do yet) and getParentId has been replaced by getParents which returns a list of longs
> * multiple parents means there is no longer a fixed root span ID; root spans just have an empty list of parents
