--- layout: doc_page --- # ResetCluster tool ResetCluster tool can be used to completely wipe out Druid cluster state stored on Metadata and Deep storage. This is intended to be used in dev/test environments where you typically want to reset the cluster before running the test suite.

It can be run in one of the following ways. ``` java org.apache.druid.cli.Main tools reset-cluster [--metadataStore] [--segmentFiles] [--taskLogs] [--hadoopWorkingPath] ``` or ``` java org.apache.druid.cli.Main tools reset-cluster --all ``` # Further Description Usage documentation can be printed by running following command. ``` java org.apache.druid.cli.Main help tools reset-cluster ``` ``` NAME druid tools reset-cluster - Cleanup all persisted state from metadata and deep storage.
