Add Virtual Machine node balancing data operations to the CDH cluster (Tutorial), cdh Virtual Machine
Note: The premise is that a new Virtual Machine node has been installed and the corresponding cdh has been installed. You can modify the host name, ip address, mac, and other operations on your own. This article only adds the cluster balance data operation to t
First of all, of course, is to download a spark source code, in the http://archive.cloudera.com/cdh5/cdh/5/to find their own source code, compiled their own packaging, about how to compile packaging can refer to my original written article:

After execution you should be able to get a compressed package similar to SPARK-1.6.0-CDH5.7.1-BIN-CUSTOM-SPARK.TGZ (the version differs depending on the

What is there in CDH? Such as:So how does this CDH software install? Cloudera Company provides a set of software to install

about CDH and Cloudera Manager
CDH (Cloudera's distribution, including Apache Hadoop), is one of the many branches of Hadoop, built from Cloudera maintenance, based on the stable version of Apache Hadoop, and integrates many patches, Can be used directly in production environments.
Cloudera Manager simplifies the installatio
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

Recently "idle" to have nothing to do, through the CM to vcores use situation to look at a glance, found that no matter how many tasks in the cluster running, the allocated vcores will never exceed 120. 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
Use yum source to install the CDH Hadoop Cluster
This document mainly records the process of using yum to install the CDH Hadoop cluster, including HDFS, Yarn, Hive, and HBase.This article uses the CDH5.4 version for installation, so the process below is for the CDH5.4 version.0. Environment Description
System Environment:
Operating System: CentOS 6.6
Hadoop version:CDH5.4
JDK version:1.7.0_71

-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)
*
/public void init (jobconf conf) throws IOException {
setconf (conf);
cluster = new cluster (conf);
Clientugi = Usergroupinformation.getcurrentuser ();
}
This is still the jobclient of the MR1 era, in/usr/lib/hadoop-mapreduce/hadoop-mapreduce-client-core-2.0.0-cdh4.5.0.jar
And/usr/lib/hadoop-0.20-mapreduce/hadoop-core-2.0.0-mr1-cdh4.5.0.jar have a jobclient, the former is the YARN age
After checking the CLASSPATH to run the Job, fix the CLASSPATH, modify the file /usr/lib
Use Windows Azure VM to install and configure CDH to build a Hadoop Cluster
