Answer Posted / Brijendra Patel
The execution plan in Pig consists of two phases: Logical Plan and Physical Plan. The Logical Plan is a high-level representation of how data should be processed based on the Pig Latin script, while the Physical Plan is a more detailed description of the actual operations that need to be performed at the MapReduce level to accomplish the same task. The Physical Plan is generated by translating the Logical Plan into a series of MapReduce jobs.
