that only InputFormat will care. When a split is required to be read, its corresponding inputsplit is passed to the InputFormat's second interface function Getrecordreader, which is then used to initialize a recordreader to parse the input data. In other words, the important information that describes split is hidden, and only specific inputformat know for themselves. It is only necessary to ensure that the inputsplit returned by Getsplits and Getrecordreader are the same implement Inputsplit.

slices for each file. For each file, the process of generating slices can be roughly summarized into the following five key steps: obtain the file path and length (1). If the file length is 0, an "empty" slice is generated (5). If the file length is not 0, obtain the data block information of the file (2). If the file format cannot be sliced, the entire file is generated as a slice (4). If the file format can be sliced, generate slices for the file (3 ). Whether the file format supports slicing

documents not from a batch of files, may come from a number of files, the two batches of files are connected, this time involves the joinIn the map phase, the map function reads two files File1 and File2 simultaneously, in order to distinguish between two sources of key/value data pairs, to label each piece of data (tag), such as tag=0 that comes from file1,tag= 2 from File2. The main task of the map phase is to label the data in different files.In the reduce phase, the reduce function obtains

When you submit a job to a Hadoop cluster, you specify the format of the job input (the default input format is textinputformat when not specified). Use the InputFormat class or InputFormat interface in Hadoop to describe the specification or format of the MapReduce job input, The InputFormat class or InputFormat interface is said to be because InputFormat is defined as an interface in the old API (hadoop-0.x), whereas in the new API (hadoop-1.x and hadoop-2.x), InputFormat is an abstract class
