Virtualization of the deployment and management of Hadoop clusters: basic operations

Not only can you deploy the Hadoop cluster very quickly at the minute level on the big data Extensions, this can be achieved by using the BDE 0 starting point-6 basic operational dimension fifth-creating the Apache Hadoop cluster with the CLI and Large Data Virtualization 0 starting point-7 basic Operation sixth Step-install big Extensions Plugin "feel." Once deployed, BDE can manage them easily, from a software-defined perspective, through a simple graphical interface and intuitive command line two methods to manage the cluster's objects. Let's start with a detailed discussion of these day-to-day requirements for cluster operation management.

Turn on and off the Hadoop cluster

Use CLI method:

1. Open Serengeti CLI, connect Serengeti server

2. Enter the command line:

Serengeti>cluster Stop--name <cluster name>

For example: Serengeti>clusterstop--name cponlycluster

3. The command line interface shows the progress of closing cluster until completed.

We then use the GUI to look at the same Hadoop cluster and try to reopen it.

1. Login vsphere Web Client, enter the big Data extensions interface

2. Enter the big Data cluster interface, you can find just shut down the Hadoop cluster also shows the stopped state.

3. Now directly in the graphical interface to reopen it, select the cluster, right-click menu select Start Big Data Cluster
