Review comment:
One way we can decouple this from specific environment variables (which may
or may not exist), is to simply remove the `-cp` section, and set `CLASSPATH`
above the call to `java`.
Something like `export CLASSPATH="$at_shaded_jar:$CLASSPATH"`
That way, the caller can simply set `CLASSPATH=/path/to/hadoop/confdir`
prior to running the `accumulo-testing` command.
We could also add a sanity check prior to running java to make sure that the
`$CLASSPATH` contains a directory with `core-site.xml` and/or `hdfs-site.xml`
(or whatever the Hadoop client configuration uses by default).
