Spark Stage. A Stage is a collection of tasks that share the same shuffle dependencies, meaning that they must exchange data with one another during execution. When a Spark job is submitted, it is broken down into stages based on the operations defined in the code. Each stage is composed of one or more tasks that can be executed …If no custom table path is specified, Spark will write data to a default table path under the warehouse directory. When the table is dropped, the default table path will be removed too. Starting from Spark 2.1, persistent datasource tables have per-partition metadata stored in the Hive metastore. This brings several benefits:2. DataFrame.count() pyspark.sql.DataFrame.count() function is used to get the number of rows present in the DataFrame. count() is an action operation that triggers the transformations to execute. Since transformations are lazy in nature they do not get executed until we call an action(). In the below example, empDF is a DataFrame object, and below …Code generation is one of the primary components of the Spark SQL engine's Catalyst Optimizer. In brief, the Catalyst Optimizer engine does the following: (1) analyzing a logical plan to resolve references, (2) logical plan optimization (3) physical planning, and (4) code generation. HTH! Many Thanks! So there is nothing explicit we need to do.
