We recommend one of Druid's other supported ingestion methods, such as [SQL-based ingestion](../multi-stage-query/index.md) or [MiddleManager-less ingestion using Kubernetes](../development/extensions-core/k8s-jobs.md). As part of this change, you must now opt-in to using the deprecated `index_hadoop` task type. If you don't do this, your Hadoop-based ingestion tasks will fail. To opt-in, set `druid.indexer.task.allowHadoopTaskExecution` to `true` in your `common.runtime.properties` file.
