Description

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.
