HBase Cluster Scale-Out

You can perform a scale-out to expand cluster capacity and improve system computing and storage capabilities. Scale-out operations incur charges. You can dynamically add nodes in response to site needs or service conditions. The cluster seamlessly manages load balancing to maintain uninterrupted service and facilitate smooth expansion of capacity.

Precautions

  • During cluster capacity expansion, the system does not automatically restart the cluster, ensuring service continuity and smooth capacity expansion.
  • If the scale-out fails, Scale-out failed is displayed in the Task Status column, and the cluster automatically rolls back to the state before the scale-out. You can try again. If you have any questions, contact technical support.
  • Only core nodes can be scaled-out.
