1.	What do you mean by spark execution plan?
Answer» A query language statement (SQL, Spark SQL, Dataframe operations, etc.) is TRANSLATED into a set of optimized LOGICAL and physical operations by an execution plan. It is a series of actions that will be CARRIED out from the SQL (or Spark SQL) statement to the DAG(DIRECTED Acyclic GRAPH), which will then be sent to Spark Executors.
