Question
How do I configure the environment when I create a ClickHouse backup task on FusionInsight Manager and set the path type to RemoteHDFS?
Answer
- Log in to FusionInsight Manager of the standby cluster.
- Choose Cluster > Services > HDFS and choose More > Download Client. Set Select Client Type to Configuration Files Only, select x86_64 for x86 or aarch64 for ARM based on the type of the node where the client is to be installed, and click OK.
- After the client file package is generated, download the client to the local PC as prompted and decompress the package.
For example, if the client file package is FusionInsight_Cluster_1_HDFS_Client.tar, decompress it to obtain FusionInsight_Cluster_1_HDFS_ClientConfig_ConfigFiles.tar, and then decompress FusionInsight_Cluster_1_HDFS_ClientConfig_ConfigFiles.tar to the D:\FusionInsight_Cluster_1_HDFS_ClientConfig_ConfigFiles directory on the local PC. The directory name cannot contain spaces.
- Go to the FusionInsight_Cluster_1_HDFS_ClientConfig_ConfigFiles\ client directory and obtain the hosts file.
- Go to FusionInsight_Cluster_1_HDFS_ClientConfig_ConfigFiles\HDFS\config to obtain the core-site.xml and hdfs-site.xml files.
- Log in to FusionInsight Manager of the source cluster.
- Choose Cluster > Services > ClickHouse, choose Configurations > All Configurations, and select backup under ClickHouse(Service).
For remote_connect_core_config_file, click Upload File and select the core-site.xml file prepared in 5.
For remote_connect_hdfs_config_file, click Upload File and select the hdfs-site.xml file prepared in 5.
- Click Save, confirm the information, and click OK to save the configuration. After saving the configurations, click Finish.
- Choose Cluster > Services > ClickHouse, click Instance, and view the instance IP address of ClickHouseServer.
- Log in to the host nodes of the ClickHouseServer instances as user root and check whether the /etc/hosts file contains the host information in 4. If not, add the host information in 4 to the /etc/hosts file.
