HBase Usage Process

The CloudTable HBase cluster mode provides a distributed, scalable, and fully managed NoSQL data storage system based on Apache HBase. It provides strong consistency and single-digit millisecond latency so it is optimal for storage and queries of massive amounts of structured and semi-structured data.

After a CloudTable HBase cluster is created, you can access it using the following methods:

• Using a client to access the cluster

  For details, see Using HBase. This section describes how to use HBase Shell to access a cluster.

• Call native open source APIs to develop HBase applications, and access the cluster through a CloudTable HBase link.

  For details, see CloudTable Service Developer Guide.

  Step	Substep	Description	Detailed Instructions
  Preparations	Creating a user and granting permissions	Before using CloudTable HBase, you need to register a Huawei Cloud account, complete real-name authentication, and grant the necessary permissions to your account. Grant the necessary service permissions to a user group, and then add users to this group to enable their access.	Creating a User and Granting Permissions
  Creating a cluster	Creating an HBase cluster	Before using HBase to execute tasks, you need to create an HBase cluster.	Creating an HBase Cluster
  Downloading the client	Downloading the HBase client	After creating a cluster, download and install the client. After the client is installed, you can use the SSH tool to connect to the cluster.	Connecting to an HBase Normal Cluster Using HBase Shell
  Preparing an ECS	-	If the client tool runs on Linux, you need to prepare a Linux ECS that is in the VPC as an HBase cluster and the Linux ECS serves as a client host. If the client tool runs on Windows, you need to prepare a Windows ECS that is in the VPC as an HBase cluster and the Windows ECS serves as a client host.	Preparing an ECS
  Installing the client	-	Place the downloaded client on the ECS, decompress the package, and install the client.	Manually Installing a Client
  Connecting to the cluster	-	After installing the MySQL client on the ECS, you can run commands to connect to the cluster and perform service operations.	Connecting to an HBase Cluster
