Front, the two pillars of hadoop , HDFS and MapReduce, We use Java to write map-reduce by placing data files of big data on HDFS. To achieve a variety of data analysis, and predict something to achieve the business value of big data, thus also reflects the value of Hadoop . NBSP, But in a traditional system, we analyze data through a database, such as a relational database: oracle Span lang= "en-US"

From physical plan to Map-reduce plan Note: Since our focus is on the pig on Spark for the Rdd execution plan, the backend references after the physical execution plan are not significant, and these sections mainly analyze the process and ignore implementation details. The entry class Mrcompiler,mrcompilier traverses the nodes in the physical execution plan in a topological order, converts them to mroperator, and each mroperator represents a map-red
