The running program on yarn is executed by container, so when we want to know how each node corresponds to the container, we need to start with it.
At first I thought yarn system command will have corresponding prompts, so yarn--help, there is no information I want. So on t

This article is the main work I have done in Hulu this year, combined with the current popular two open source solutions Docker and yarn, provide a flexible programming model, currently supporting the DAG programming model, will support the long service programming model.
Based on Voidbox, developers can easily write a distributed framework, Docker as a running execution engine, yarn as a management sys

Recently, I often see people on Weibo saying, "many companies do not use yarn for the time being, because the cluster size of a company is not as large as that of Yahoo or Facebook, even tens of thousands in the future ". This is completely a wrong idea. In the era of hadoop's rapid development, it must be corrected.
In fact, the above idea only shows the scalability of yarn. scalability is a feature that i
This article mainly understands the memory allocation in the spark on yarn deployment mode, because there is no in-depth study of the spark source code, so only the log to see the relevant source code, so as to understand "why this, why that." Description
Depending on how the driver is distributed in the Spark application, there are two modes of Spark on yarn: yarn
YARN, and why one or May is better in Global resource management than the other. There ' s a lot of contention in two camps between the methods and the intentions S.
Mesos is built to is a global resource manager for your entire data center. YARN is created as a necessity to move the Hadoop MapReduce API to the next iteration and life cycle. It had to remove the resource management out of that embedded fra
