A brief introduction to CDHEveryone often says CDH, whose full name is: Cloudera's distribution including Apache Hadoop, simply Cloudera's Hadoop platform, is encapsulated and reinforced on the basis of Apache native Hadoop components. What is there in CDH? Such as:So how does this CDH software install? Cloudera Company provides a set of software to install

First of all, to ask, what is CDH?To install a Hadoop cluster that deploys 100 or even 1000 servers, package I including hive,hbase,flume ... Components, a day to build the complete, there is to consider the system after the update asked questions, then need to CDH Advantages of the CDH version:Clear Version DivisionFaster version updateSupport for Kerberos secur

Cloudera Manager and CDH 5.14.0 Installation Process in CentOS 7 As we all know, the configuration of Apache Hadoop is cumbersome and fragmented. For this reason, Cloudera provides the Clouder Manager tool and encapsulates Apache Hadoop, flume, spark, hive, hbase and other big data products form CDH products with their own characteristics, and then use CM for installation. This facilitates cluster construct

The available vcores for the cluster are 360 (15 machines x24 virtual cores). That's equivalent to 1/3 of CPU resources, and as a semi-obsessive-compulsive disorder, this is something that can nev

-source solution. In Hadoop, JobTracker generally does not have to solve the error tolerance of JobTracker because the failure probability of JobTracker is much lower than that of NameNode. In the latest version 4.2.0, Cloudera provides a complete set of JobTracker HA solutions. This article will introduce this solution. Before introducing the CDH solution, briefly introduce the basic workflow of JobTracker HA, which can be summarized as follows: (1)

Recently, a Hadoop cluster was installed, so the HA,CDH4 that configured HDFS supported the quorum-based storage and shared storage using NFS two HA scenarios, while CDH5 only supported the first scenario, the Qjm ha scenario. About the installation deployment process for Hadoop clusters You can refer to the process of installing CDH Hadoop clusters using Yum or manually installing Hadoop clusters.
