title: Long time index recovery when install plugin into existing Elasticsearch
body: <p>I installed <a href="https://github.com/jprante/elasticsearch-langdetect" rel="nofollow noreferrer">langdetect</a> plugin into Elasticsearch beta cluster that have just 1 node and around 455 indices. When re-start server, use around 5-10 minutes to get yellow status.</p>
  
  <p>I think if this plugin be installed in production that have many nodes and thousand indices. It have to use a lot of time to recovery perhaps.</p>
  
  <p>Anyone used to meet this situation like this? how could you deal with it? Could I re-start ES with zero downtime?</p>
  
  <p>p.s. use ES version 5.3.2</p>
