splits and constructs a resource request for all mapsMr AM is doing the necessary preparation for Mr OutputcommitterMR am initiates a resource request to RM (Scheduler), obtains a set of container for the Map/reduce task to run, and, together with NM, performs some necessary tasks for each container, including resource localization, etc.The MR AM monitors the running task until it finishes, and when the task fails, it requests a new container to run the failed taskWhen each map/reduce task is c

In the image of Hadoop Technology Insider: An in-depth analysis of the principles of MapReduce architecture design and implementation, I've drawn a similar figure with my hand-_-4 Majority: Hdfs,client,jobtracker,tasktrackerYarn's idea is to separate resource scheduling from job control, thereby reducing the burden on a single node (jobtracker). Applicationmaster equivalent to Jobtracker in the operation control, ResourceManager equivalent to TaskScheduler.MapReduceV1 work life cycle plots and b

Recent work needs, groping to build a Hadoop 2.2.0 (YARN) cluster, encountered some problems in the middle, in this record, I hope to help students need. This article does not cover hadoop2.2 compilation, compilation-related issues in another article, "Hadoop 2.2.0 Source Compilation Notes", this article assumes that we have obtained the Hadoop 2.2.0 64bit release package. Due to spark compatibility issues, we later used the version of the Hadoop 2.0.
