Subject [jira] [Commented] (ACCUMULO-3741) Reduce incompatibilities with htrace 3.2.0-incubating
Date Sat, 18 Apr 2015 00:58:59 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3741?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14500982#comment-14500982

Christopher Tubbs commented on ACCUMULO-3741:
---------------------------------------------

Will we want to switch to 3.2.0-incubating in the 1.7.0 release? Or, are we looking at this
for 1.8.0?

> 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 * Spans can now have multiple parents (although none do yet) and getParentId has been
replaced by getParents which returns a list of longs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
