Hi, everyone!
I want to know the block information about So, I ask you something about the container. 1. Is the NodeManager knows the information about block, especially blockid? If is not, then is there any way to get block information from datanode? 2. How can communicate between container and NodeManager? 3. In addition, How the communication happens between NodeManager and DataNode? 4. In the level of container, container has an instance of YARNChild, and YARNChild can run the instance of MapTask and ReduceTask, right? But where is the features of JobTracker and TaskTracker in either container or YARNChild? Thank you for considering my questions!
