[misilot]

Hello,

What is the purpose of deleting and recreating the plugin directory?

ansible-elasticsearch/tasks/main.yml

Lines 23 to 26 in 558f681

	- file: path={{ elasticsearch_plugin_dir }} state=absent
	when: elasticsearch_plugin_dir is defined
	- file: path={{ elasticsearch_plugin_dir }} state=directory owner={{ elasticsearch_user }} group={{ elasticsearch_group }} recurse=yes
	when: elasticsearch_plugin_dir is defined

Thanks!
