title: AWS Glue executor memory limit
body: <p>I found that AWS Glue set up executor's instance with memory limit to 5 Gb <code>--conf spark.executor.memory=5g</code> and some times, on a big datasets it fails with <code>java.lang.OutOfMemoryError</code>. The same is for driver instance <code>--spark.driver.memory=5g</code>.
  Is there any option to increase this value?</p>
