sandynz opened a new issue, #37821:
URL: https://github.com/apache/shardingsphere/issues/37821
## Bug Report
### Which version of ShardingSphere did you use?
master branch
commit: 3d9fd0d3e825de0305cad2bc140c79dd459b95c3
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
proxy
### Expected behavior
1. `pg_catalog.gs_job_argument` metadata is complete (Critical)
2. When metadata is not complete, restarting proxy could start successfully
(Optional)
### Actual behavior
I'm testing on local proxy, and kill proxy sometimes, the latest kill and
start proxy got error.

/>
### Reason analyze (If you can)
Possible reason: Proxy is persisting metadata nodes, and proxy is killed at
the moment, it left uncomplete node in ZK.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
### Example codes for reproduce this issue (such as a github link).
