Elasticsearch fails to start with index and alias names need to be unique error
<p>I have elasticsearch integrated into my app for a long time now. Since, a couple of days ago I get this weird behaviour. My elasticsearch instance is not starting. Following is the error I get. I tried to uninstall and reinstall elasticsearch but, that didn't work.</p>

<p>java.lang.IllegalStateException: index and alias names need to be unique, but alias [orders_development] and index [orders_development] have the same name</p>
