[jira] [Commented] (HBASE-9683) Port HTrace support to 0.94

    [ https://issues.apache.org/jira/browse/HBASE-9683?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13781478#comment-13781478 ] 

Elliott Clark commented on HBASE-9683:
--------------------------------------

This breaks wire compat correct ?

Also there are much newer versions of HTrace that have change the user facing api, and added some perf gains.  So my preference would be to use 2.0.1 if we even want this in 0.94

> Port HTrace (HBASE-6524) to 0.94. This patch includes a wire-format change on writable RPC. It serializes the traceID and spanID in class Invocation. This should be compatible with old versions.
