Accumulo 1.7.0 should have the necessary slf4j jars in
ACCUMULO_HOME/lib. The log4j jar should be pulled automatically from
your Hadoop distribution.
Are you using some vendor's version of Hadoop or did you get it from
Apache (and what version is it)?
Can you please verify the values for HADOOP_PREFIX in accumulo-env.sh?
Can you also make sure that you don't have any incorrect values for
HADOOP_PREFIX or ACCUMULO_HOME in your current environment (check `env`)?

Any thoughts?

Are the jars readable by the user running the Accumulo process?
