4.1. Redeploy all Clusters

When making gateway-wide changes, such implementing Kerberos or SSL, or if you change the system clock, you must redeploy all the Cluster Topologies.

To redeploy all Cluster Topologies:

Verify the timestamp on the currently deployed clusters.

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 all clusters.
```
bin\knoxcli.cmd redeploy
```

Verify that a new cluster WAR was created.

cd $gateway_home
dir data\deployments

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

04/17/2014  05:34 PM    <DIR>          .

               0 File(s)              0 bytes
               8 Dir(s)   9,730,850,816 bytes free

A new file for each with the current timestamp is created.
