-----------------------------------

I don't see any directory creation code there, can you be more specific?

> On client code, when one calls TokenUtil.obtainToken it loads ProtobufUtil which in its static block initializes DynamicClassLoader and that creates the directory ${hbase.rootdir}/lib
> https://github.com/apache/hbase/blob/master/hbase-common/src/main/java/org/apache/hadoop/hbase/util/DynamicClassLoader.java#L115-L127
> Since this is region server specific code, not expecting this to happen when one accesses hbase as a client.
