This topic describes how to disable auto scaling when your business volume stabilizes.

Background information

After auto scaling is disabled, all task nodes added by using auto scaling are released. However, the data of core nodes stored in HDFS is not affected. If a cluster has insufficient computing resources after you disable auto scaling, we recommend that you scale out the cluster to increase computing resources. For more information, see Scale out a cluster.
