Subject [jira] [Commented] (ACCUMULO-4171) Update to htrace-core4
Date Wed, 06 Jul 2016 21:12:11 GMT

Christopher Tubbs commented on ACCUMULO-4171:
---------------------------------------------

I'm interested in using a modern version... but I don't think my concerns have been alleviated
about API stability, and compatibility between Accumulo, Hadoop, and HTrace versions.

> We are currently using HTrace 3.1.0-incubating. There were some API changes and improvements
on the way to HTrace 4.x-incubating, and we should stay up to date with those changes.
> Currently you can extend Accumulo tracing down into HDFS if you're using Accumulo 1.7
and Hadoop 2.7. This ticket is for continuing to make that work for versions of Hadoop >
2.7.
