body: <p>I need to parse my Date and it gives me an error.</p>
  
  <pre><code>input {  
    file {
      path =&gt; "/home/osboxes/ELK/logstash/data/data.csv"
      start_position =&gt; "beginning"    
    }
  }
  filter {  
    csv {
        separator =&gt; ","
        columns =&gt; ["Date","Open","High","Low","Close","Volume","Adj Close"]

    mutate {convert =&gt; ["High", "float"]}
    mutate {convert =&gt; ["Open", "float"]}

  }

  <p>The data.csv when I'm reading this is like this:</p>
  
  <pre><code>Date,Open,High,Low,Close,Volume,Adj Close
  2015-04-02,125.03,125.56,124.19,125.32,32120700,125.32
  2015-04-01,124.82,125.12,123.10,124.25,40359200,124.25
  </code></pre>
  
  <p>Where am I missing? Thanks in advance.</p>
  
  <p>My logstash terminal only say this:</p>
  
  <pre><code>$ bin/logstash -f /home/osboxes/ELK/logstash/logstash.conf 
  Settings: Default pipeline workers: 2
  Pipeline main started
