Subject overwrite app
Date Tue, 16 Apr 2013 07:45:51 GMT
Hi,while S4 zkserver is running and the cluster and nodes is already deployde,now I overwrite
the app again.I use the command "./s4 s4r " package the app,and redeploy the app onto the
cluster.However,it doesn't work!The log is below:

[root@202 myApp]# ./s4 deploy -s4r=`pwd`/build/libs/myApp.s4r -c=cluster1 -appName=myApp -zk=
calling referenced s4 script : /root/apache-s4-0.6.0-incubating-bin/s4
23:31:49.891 [main] INFO - Using specified S4R [file:/tmp/s4share/myApp/build/libs/myApp.s4r]
23:31:50.207 [main] WARN  org.apache.s4.deploy.DeploymentUtils - Node /s4/clusters/cluster1/app/s4App
already exists, will not overwrite

It warns that s4App already exists and overwriting the app is not allowed.How can I redeploy
the overwrited app onto the cluster without reboot the zkServer?
