title: NameError: name 'dbutils' is not defined in pyspark
body: <p>I am running a pyspark job in databricks cloud. I need to write some of the csv files to databricks filesystem (dbfs) as part of this job and also i need to use some of the dbutils native commands like,</p>
  
  <pre><code>#mount azure blob to dbfs location
  dbutils.fs.mount (source="...",mount_point="/mnt/...",extra_configs="{key:value}")
  </code></pre>
  
  <p>I am also trying to unmount once the files has been written to the mount directory. But, when i am using dbutils directly in the pyspark job it is failing with </p>
  
  <pre><code>NameError: name 'dbutils' is not defined
  </code></pre>
  
  <p>Should i import any of the package to use dbutils in pyspark code ? Thanks in advance.</p>
