Hi, The NameNode splits the job into several tasks and submits to the different DataNode(i.e nodes) , the split size varies from 64KB to 128MB. The NameNode assigns the data split to a datanod.
Namenode actually has a table to store the mappings of data node and block stored in it. it is possible to query the namenode and get data from it.
