In the latest release of the Hortonworks HDP Sandbox version 2.2, HBase starts with an error, because the new version of HBase's storage path is different from the past, and the startup script still inherits the old command line to start HBase, The hbase-daemond.sh file could not be found and failed to start. See, the 2.2 version of the sandbox release a little hasty, so obvious and simple mistakes should not appear. Here's how to fix the problem:The

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

Whether the two days have been quietly Yarn by the screen, Facebook recently released a new Node.js Package Manager Yarn to replace NPM. In order to keep up with the trend of Javascript, I might have tasted this claim to be fast and reliable and safe package management, so the writing will not be very detailed, more likely just for this new package management and NPM differences between. There ma
, dremel is usually used in combination with mr. The design motivation is not to replace Mr, but to make computing more efficient in some scenarios. In addition, dremel and Impala are computing systems that require computing resources but are not integrated into the currently developing resource management system yarn. This means that if impala is used, you can only build an independent private cluster and cannot share resources. Even if impala is mat

what is Yarn.
This refers to the description of the Civil service network:Yarn is a dependency management tool. It manages your code and shares the code with developers around the world. Yarn is efficient, safe and reliable, and you can safely use it.
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

Source-level analysis, you will find the code is very difficult to read, often because a class did too many things, the code amount of more than 3,000 lines, resulting in a class task is not clear, increase the difficulty of bug repair and version maintenance.
