reset elasticsearch node

I know you can delete the data directory on a percona cluster server, and then let it join the cluster again. This will result in a full transfer of data; this has been useful a couple of times. Is the same possible in an elasticserach cluster? i.e. shutdown one elastic node. If the cluster health is still yellow, is it safe to delete data in that one node ../elasticsearch/indices/* and then join cluster again as 'new' node?
