Downloading the Client

Scenario

Use the default client provided by MRS clusters to manage the cluster, run services, and perform secondary development. Before you use this client, you need to download its software package.

Procedure

Log in to FusionInsight Manager.
Choose Cluster > Dashboard. In the upper right corner, click More > Download Client.

For MRS 3.3.0 or later, the Cluster > Dashboard page has been removed from FusionInsight Manager.

The Download Cluster Client dialog box is displayed.

Figure 1 Downloading the cluster client
Select a client type for Select Client Type.
- Complete Client: the package contains scripts, compilation files, and configuration files.
- Configuration Files Only: the package contains only the client configuration files.
  This type is applicable to application development tasks. For example, after a complete client is downloaded and installed, the cluster administrator modifies the service configuration on FusionInsight Manager, and developers need to update the client configuration files.
The two platform types (x86_64 and aarch64) correspond to x86 and ARM nodes, respectively. Select the platform type based on the architecture types of the nodes where you will install the client.
Determine whether to generate a client software package file on the cluster node.
- If yes, select Save to Path and click OK to generate the client file.
  The generated file is stored in the /tmp/FusionInsight-Client directory on the active management node by default. You can also store the client file in other directories, and user omm has the read, write, and execute permissions on the directory. If the client file already exists in the path, the existing client file will be replaced.
  
  After the file is generated, copy the obtained package to another directory, for example, /opt/Bigdata/hadoopclient, as user omm or client installation user.
- If no, click OK to download the client file to the local host.
  The system starts to download the client software package.
