This seems to be the issue.

Make that directory writable by the elasticsearch user. That is more of a sysadm issue that an Elasticsearch issue though so may depend on operating system used and where you have deployed it.

It is not an Elasticsearch issue but rather related to system administration. As I said earlier it will depend on your environment so I would recommend you google it.
