So I am trying to track down why we upgraded commons config from 1.6 to 1.10. This upgrade is problematic for a bug fix release for a few reasons. For one, the changes in 06d80292 <https://github.com/apache/accumulo/pull/659> break semver by adding new methods inherited from ClientConfiguration. Then Keith ran into problems trying to run Map Reduce for continuous ingest. Keith opened an issue here: https://github.com/apache/accumulo/issues/1065
I don't think this change should go in a bug fix release but I think it would be good to know why this was done in the first place. I am going to test a branch with this upgrade reverted.
