configuration, when exception occur etc.
I only configured server.yaml
`mode:
type: Cluster
repository:
type: ZooKeeper
props:
namespace: pulsar
server-lists: xxx:2181
retryIntervalMilliseconds: 500
timeToLiveSeconds: 60
maxRetries: 3
operationTimeoutMilliseconds: 500
overwrite: false
rules:
- !AUTHORITY
users:
- root@%:root
- sharding@:sharding
provider:
type: ALL_PERMITTED
`
### Example codes for reproduce this issue (such as a github link).
Pull the master code and modify the server.xml
