title: Why SparkSession.sql("set hive.support.quoted.identifiers=None") doesn't work?
body: <p>I want to use regular-expression in SparkSession.sql, but it doesn't work whether i use :</p>
  
  <p><code>SparkSession.builder.enableHiveSupport().config("hive.support.quoted.identifiers", None)</code> </p>
  
  <p>or </p>
  
  <p><code>SparkSession.sql("set hive.support.quoted.identifiers=None")</code>.</p>
  
  <p>Please tell me how to do it.</p>
  
  <p>The code:</p>
  
  <pre class="lang-py prettyprint-override"><code>ss = (pyspark.sql.SparkSession
        .builder
        .enableHiveSupport()          
        .config("hive.support.quoted.identifiers", None)
        .getOrCreate())                                         
  #ss.sql("set hive.support.quoted.identifiers=None")
  ss.sql("SELECT `(col)?+.+` FROM table")
  </code></pre>
  
  <p>program result:</p>
  
  <pre><code>pyspark.sql.utils.AnalysisException: "cannot resolve '`(col)?+.+`' given input columns: ... ...
  </code></pre>
