This command produces the following error:

./bin/runmr filedata.CharacterHistogram -t dataTable --auths exampleVis --vis exampleVis

Exception in thread "main" java.lang.IllegalStateException: Bad configuration: the store method was not called.

The exception above can be corrected by updating the class to call the store method as needed. But this only leads to follow-on errors. There have been several methods updated between 1.10 and 2.x. Several methods have been deprecated as well. At this point the filedata example most likely should be re-factored to work with Accumulo 2.x.
