# 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.
|
||
|
|
ResetCluster automatically figures out necessary information from Druid cluster configuration. So the java classpath
|
||
|
|
used in the command must have all the necessary druid configuration files.
|
||
|
|
|
||
|
|
It can be run in one of the following ways.
|
||
|
|
|
||
|
|
```
|
||
|
|
java io.druid.cli.Main tools reset-cluster [--metadataStore] [--segmentFiles] [--taskLogs] [--hadoopWorkingPath]
|
||
|
|
```
|
||
|
|
|
||
|
|
or
|
||
|
|
|
||
|
|
```
|
||
|
|
java io.druid.cli.Main tools reset-cluster --all
|
||
|
|
```
|
||
|
|
|
||
|
|
# Further Description
|
||
|
|

|
||
