1. Read the table structure to import the data, generate the run class, default is QueryResult, hit the jar package, and then submit it to Hadoop2. Set up the job, the main is to set the above sixth chapter of the various parameters3. This is where Hadoop executes the MapReduce to execute the import command,1) The first thing to do is to slice the data, i.e. DatasplitDatadrivendbinputformat.getsplits (Jobcontext Job)2) After splitting the range, write the range to readDatadrivendbinputformat.wri
