Objectives:
I used cloudera Manager server to install and manage hadoop clusters. I heard that general enterprises use cloudera to install and manage hadoop. I also want to try it. I checked the data for a day and found that cloudera is very mature, in addition, the installation methods of pseudo do distributed and cloudera
Cloudera cdh4 has three installation methods:
1. Automatic Installation through cloudera Manager (only 64-bit Linux operating systems are supported );
2. Use the yum command to manually install the package;
3. Manually install the tarball package;
I personally recommend that you try either method 1 or 2. You should first have a clear understanding of the hadoop architecture, built-in components, and configu
After the Cloudera Manager server and Agent are started, you can configure the CDH5 installation.You can then test the 7180 port of the master node through the browser (since the boot of the CM server takes some time, this may take a while to access), and the default user name and password are admin.making a local sourceDownload CDH to local http://archive-primary.cloudera.com/cdh5/parcels/5.3.4/first,Here are three things to download,The first is the
Arrogant data room environmental monitoring System after the concept was proposed, which company received the most attention? Not the traditional IT industry giants, nor the fast-rising internet companies, but Cloudera. Those who believe that the real big data in the enterprise should know this company. For just 7 years, Cloudera has become the most important member of the Hadoop ecosystem, both in commerci

Cloudera impala is an engine that runs distributed queries on HDFS and hbase.This source is a snapshot of our internal development version. We regularly update the version.This readme document describes how to use this source to build cloudera Impala. For more information, see:

Impala is a new query system developed by cloudera. It provides SQL semantics and can query Pb-level big data stored in hadoop HDFS and hbase. Although the existing hive system also provides SQL semantics, the underlying hive execution uses the mapreduce engine and is still a batch processing process, which is difficult to satisfy the query interaction. In contrast, Impala's biggest feature is its speed. Impala provides a real-time SQL query interface
Services:haddoop components that can be deployed on cluster, such as Hdfs,yarn,hbase.Roles: When the service is configured, it is created by Cloudera Manager. For example, Namenode is a role of the HDFs service.Role group: The management of role can divide the same category of roles (such as datanode) into different role groups. Each role group can have its own series of configurations.Role Instance: A single instance (which can be considered a proces
