  InputSplit in Hadoop

When a Hadoop job is run, it splits input files into chunks and assign each split to a mapper to process. This is called InputSplit.In YARN, when a MapReduce job is started, the Resource Manager (the cluster resource management and job scheduling facility) creates an Application Master daemon to look after the lifecycle of the job. (In Hadoop 1, the JobTracker monitored individual jobs as well as handling job scheduling and cluster resource management.)
