Subject [jira] [Commented] (ACCUMULO-4171) Update to htrace-core4
Date Fri, 25 Mar 2016 20:56:25 GMT


Christopher Tubbs commented on ACCUMULO-4171:

Do we know how stable htrace's API is going to be as it moves forward from here on? Does htrace
have an API statement, like semver?

My concern is that now that Hadoop and Accumulo are both using HTrace, updating HTrace might
further constrain the Hadoop versions we support (same with not updating it). If HTrace's
API is not stable (or if Hadoop or ourselves use items which are not in HTrace's declared
stable API), we may be limited to using only the exact version that Hadoop is using.

on the way to HTrace 4.x-incubating, and we should stay up to date with those changes.
