Description of problem:
Mysql data couldn't be resotred to a new scalable jbossews app, it can't connect to mysql shell as below:
[myscalapp1-jingdev1.dev.rhcloud.com ~]\> mysql
ERROR 1130 (HY000): Host '' is not allowed to connect to this MySQL server

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Create an scaling  jbossews  app
rhc app create -a app1 -t  jbossews-1.0  -s

2. Disable auto scaling by:
create new file $APP_Dir/.openshift/markers/disable_auto_scaling
cd $APP
touch .openshift/markers/disable_auto_scaling
git commit -a -m "disable_auto_scaling"
git push

3. Scale up by rest API

4. Add mysql to the app
#rhc cartridge add mysql-5.10 -a app1

5. Write some data to mysql

6. Snapshot save this app
#rhc snapshot save app1 -p xx

7. Delete this app
#rhc delete app app1 --confirm

8. Repeat step 1 to 4 to create a new scalable app with mysql added.

9. Restore snapshot
#rhc snapshot restore app1 -f ./app1.tar.gz

10. SSH into the app and check mysql data

Actual results:
It can't connect to mysql.

Expected results:
Mysql shell can be accessed, and data is restored.

Additional info:
1. It works well if snapshot restored to an existing scalable app.
2. It's also reproduced in other cartridges, like php-5.3.

Above is merged in devenv-2340, move it to ON_QA to verify
Comment 3 joycezhang 2012-10-17 01:06:42 EDT
This bug has been verified on devenv_2340 with rhc-0.99.7.gem client. It's fixed. mysql can be accessed after the new created scalable app restored, and data is back as well. So mark it as Verified.Thanks.
