title: Install Delta Lake libraries on a server without internet access
body: <p>I have a server without internet access where I would like to use Delta Lake.
  So the normal use of Delta lake in the spark session does not work.
  from pyspark.sql import SparkSession</p>
  <pre><code>spark = SparkSession \
     .builder \
     .appName(&quot;...&quot;) \
     .master(&quot;...&quot;) \
     .config(&quot;spark.sql.extensions&quot;, &quot;io.delta.sql.DeltaSparkSessionExtension&quot;) \
     .config(&quot;spark.sql.catalog.spark_catalog&quot;, &quot;org.apache.spark.sql.delta.catalog.DeltaCatalog&quot;) \
     .getOrCreate()
  </code></pre>
  <p>Where shall I copy the Delta-lake github repository?
  How can I point the spark session to the right libraries</p>
