leizhiyuan opened a new issue, #15448:
URL: https://github.com/apache/pulsar/issues/15448
**Describe the bug**
if we create a namespace a， we will write some node in zk
maybe /namespaces/a ,/admin/policies/a. /balance/a some nodes were created
then we delete namespace a, and the pulsar will delete in zk
if deleting /namespaces/a succeeds, but admin/policies/a occurs error, we
return an error for the client
but if they delete twice, we judge `/namespaces/a` was deleted, we won't go
to the next step
then the zookeeper node will leak.
**To Reproduce**
Steps to reproduce the behavior:
1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error
**Expected behavior**
how to keep atomicity in metastore when deleting, if fail,all fail,if
succeeds,all succeed
