Mike Drob commented on HBASE-19920:
-----------------------------------
I'm not very happy with this test because we're still only testing the side
effects of "did dynamic class loader load" instead of the actual effects we
care about preventing (did file system access occur) but given all the static
methods at play here, I think this is the best we're going to do.
> TokenUtil.obtainToken unnecessarily creates a local directory

> On client code, when one calls TokenUtil.obtainToken it loads ProtobufUtil
> which in its static block initializes DynamicClassLoader and that creates the
> directory ${hbase.local.dir}/jars/ and also instantiates a filesystem class
> to access hbase.dynamic.jars.dir.
> https://github.com/apache/hbase/blob/master/hbase-common/src/main/java/org/apache/hadoop/hbase/util/DynamicClassLoader.java#L109-L127
> Since this is region server specific code, not expecting this to happen when
> one accesses hbase as a client.
