Link: http://hortonworks.com/kb/get-started-setting-up-ambari/ Ambari is 100% open source and supported ded in HDP, greatly simplifying installation and initial configuration of hadoop clusters. in this article we'll be running through some installation steps to get started with ambari. most of the steps here are covered in the main HDP documentation here. Ambari is a 100% open-source project that is in

Cygwin is a good tool. It can be used in a Linux environment running in windows. It is a compromise when integrating eclipse development. You may also encounter some problems. 1. Installation: many tools are not installed by default during installation, such as VI and SSH. You need to select the Installation tool. 2. path, in the cygwin format, for example, replacing "D: \ cygwin" with "/cygdrive/D/cygwiw". If the directory contains spaces, problems may occur, the path in the cygdrive format

based on the recommended configuration of Horntonworks, a common memory allocation scheme for various components on Hadoop cluster is given. The right-most column of the scenario is a 8G VM allocation scheme that reserves 1-2g memory to the operating system, assigns 4G to Yarn/mapreduce, and of course includes hive, and the remaining 2-3g is reserved for hbase when it is necessary to use HBase.

JMX, these monitoring methods are Zabbix server initiative to ask the equipment to be monitored, and trapper is passively waiting for the monitoring equipment to report the data (through Zabbix_sender) up, Then extract what you want from the data in the report. Note If the monitor side provides an interface for external access to its running data (not too secure), you can use the external check invoke script to remotely fetch the data and then zabbix_sender the obtained data to Zabbix Server i
