title: read a file of JSON string in pyspark
body: <p>I have a file look like this:</p>
  <pre><code>'{&quot;Name&quot;: &quot;John&quot;, &quot;Age&quot;: 23}'
  '{&quot;Name&quot;: &quot;Mary&quot;, &quot;Age&quot;: 21}'
  </code></pre>
  <p>How can I read this file and get a pyspark dataframe like this:</p>
  <pre><code>     Name   | Age
      &quot;John&quot;  | 23
      &quot;Mary&quot;  | 21
  </code></pre>
