+# a) directories immediately containing jars with plugins and their dependencies
+# b) uber-jars with plugins and their dependencies
+# c) directories immediately containing the package directory structure of classes of plugins and their dependencies

+# plugin.path=/usr/local/share/java,/usr/local/share/kafka/plugins,/opt/connectors,
