Here are some recent issues I opened that would be good for a new developer to work on: https://github.com/apache/accumulo-testing/issues/53 https://github.com/apache/accumulo-examples/issues/35
I also recently discovered the static analysis site LGTM has found a lot of small things which may be good work for someone new to the project: https://lgtm.com/projects/g/apache/accumulo/
