4.2. Redeploy Specific Clusters

When making changes that impact a single cluster, such as changing an alias or restoring from an earlier cluster topology descriptor file, you only redeploy the effected cluster.

To redeploy a specific cluster:

Verify the timestamp on the currently deployed Cluster Topology WAR files.

cd $gateway_home
dir data\deployments

Directory of C:\hdp\knox-0.4.0.2.1.1.0-1557\data\deployments

04/17/2014  05:30 PM    <DIR>          .
04/17/2014  05:30 PM    <DIR>          ..
04/17/2014  05:30 PM    <DIR>          cluster.war.145514f4dc8
04/17/2014  05:30 PM    <DIR>          myCluster.war.145514f4dc8
04/11/2014  08:35 AM    <DIR>          sandbox.war.145514f4dc8
               0 File(s)              0 bytes
               5 Dir(s)   9,730,977,792 bytes free

Redeploy a specific cluster.
```
cd $gateway_home
bin\knoxcli.cmd redeploy --cluster myCluster
```
-
where $cluster_name is the name of the cluster topology descriptor (without the XML extension). For example, myCluster.

Verify that the cluster was deployed.

cd $gateway_home
dir data\deployments

Directory of C:\hdp\knox-0.4.0.2.1.1.0-1557\data\deployments

04/17/2014  05:30 PM    <DIR>          .
04/17/2014  05:30 PM    <DIR>          ..
04/17/2014  05:30 PM    <DIR>          cluster.war.145514f4dc8
04/17/2014  05:30 PM    <DIR>          myCluster.war.145514f4dc8
04/17/2014  05:34 PM    <DIR>          myCluster.war.1457241b5dc
04/11/2014  08:35 AM    <DIR>          sandbox.war.145514f4dc8
               0 File(s)              0 bytes
               5 Dir(s)   9,730,977,792 bytes free

A new file with the current timestamp is created.
