title: How to remove elasticsearch?
body: <p>I am trying to make logstash work with elasticsearch and Kibana. I had all the latest versions, but after I faced a few problems, I realized that I needed to install an older version, i.e., 0.20.6, of elasticsearch in order for it to work correctly with the latest version of logstash. So, I downloaded the older version, did an <code>rm -rf</code> of the older (v.0.90.x) one and installed the new (v.0.20.6) one. I tried to start it up. It starts, but then gives me repeating errors like: </p>

  <p>As you can see, it is still trying to look for the v.0.90.x installation. My <code>localhost:9200</code> shows the following output:</p>
  
  <pre><code>{
    "ok" : true,
    "status" : 200,
    "name" : "Blob",
    "version" : {
      "number" : "0.90.2",
      "snapshot_build" : false,
      "lucene_version" : "4.3.1"
    },
    "tagline" : "You Know, for Search"
  }
  </code></pre>
  
  <p>How do I solve this to use v.0.20.6?</p>
