title: Remove of data folder is not synced in Elasticsearch upon index delete
body: <p>We have an ES cluster with 2 nodes. When we delete an index not all folders in the cluster (on filesystem) are deleted which causes some problems when restarting one server.</p>
  
  <p>Then our deleted indices gets distributed with some weird state indicating that the cluster health is not green.</p>
  
  <p>Example. We delete index with name someIndex and after deletion we check file system, one can see this:</p>
  
  <p>Node1<br>
  ElasticSearch\data\clustername\nodes\0\indices\<br>
  ElasticSearch\data\clustername\nodes\1\indices\</p>
  
  <p>Node2<br>
  ElasticSearch\data\clustername\nodes\0\indices\ 
  ElasticSearch\data\clustername\nodes\1\indices\someIndex (&lt;-- still present)</p>
  
  <p>Anyone know whats causing this?</p>
  
  <p>ES-version: 0.90.5</p>
