The MapR quick installer automates the process of configuring a Hadoop cluster and installing MapR software based on node type. You can install the MapR distribution for Hadoop on a set of nodes from any machine that can connect to the nodes. Using the quick installer, you can configure each node in a MapR cluster as one of the following types:
- Control Node: Control nodes manage the operation of the cluster. Control nodes host the ZooKeeper, CLDB, JobTracker, ResourceManager, and Webserver services. One control node also hosts the HistoryServer.
- Data Nodes: Data nodes host the NodeManager, TaskTracker, and FileServer services. These nodes store data, run YARN applications and MapReduce jobs, and process table data.
- Control-as-Data Nodes: Control-as-data nodes combine control and data node functionality. This node type is appropriate for small clusters.
- Client Nodes: Client nodes provide controlled user access to the cluster.
Ecosystem Component Installation
In addition to installing the core components of the MapR Hadoop distribution, the MapR quick installer supports installation of Apache Spark, Hive, and HBase. To install the Spark and Hive ecosystem components, you must use the quick installer configuration file. You can also use the configuration file to install HBase, however when you run the quick installer in interactive mode, the installer prompts you to see if you want HBase or MapR-DB installed. Entering y at these prompts instructs the installer to install HBase and/or MapR-DB during the installation process.
Installation Steps
To successfully install MapR using the quick installer, complete the following steps:
- Make sure your installation machine and nodes meet all of the prerequisites.
- Prepare for the installation and set up the installation machine.
- Run the quick installer.
- Complete the post installation steps.
Prerequisites
Verify that your installation machine and the nodes that you plan to install MapR on meet the required prerequisites.
Installation Machine Prerequisites
The machine from which you run the quick installer must run one of the following operating systems:
- Ubuntu 12.04 or later
- RedHat (with the EPEL repository installed) 6.1 or later
- CentOS (with the EPEL repository installed) 6.1 or later
- SuSE
- To install from a machine running SuSE, you must create a symbolic link named libssl.so.10, that points to libssl.so.1.0.0 under /usr/lib64 before you install.
- Example:
<syntaxhighlight> cd /usr/lib64 ln -s libssl.so.1.0.0 libssl.so.10 <bash/>
