> We are no longer packaging log4j, and it needs to be on our classpath before the classloader
can read modifications to general.classpaths in the accumulo-site.xml file.  Line 84 of the
accumulo script looks for the log4j in two possible hadoop subdirectories, but if it isn't
in either of those accumulo init will not run (thanks to [~vines] for tracking this down).

> If we can't come up with a reasonable way to address the issue, we should at least document
