----------------------------------------
Summary: Reduce incompatibilities with htrace 3.2.0-incubating
Key: ACCUMULO-3741
URL: https://issues.apache.org/jira/browse/ACCUMULO-3741
Project: Accumulo
Issue Type: Bug
Reporter: Billie Rinaldi
Assignee: Billie Rinaldi
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has been replaced by getParents which returns a list of longs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
