集群部署hugegraph1.2.0 ，默认的hugegraph图创建属性可以同步到其他节点，但是在主节点创建图同步失败，是因为什么原因造成的？

Hey @chenhong1990, it seems like you're encountering an issue with graph synchronization in a clustered deployment of HugeGraph 1.2.0. From what you've described, the default graph properties are syncing across nodes, but creating a graph on the master node fails to sync. This could be due to a few reasons:

1. Configuration Issues: Ensure that all nodes in your cluster are correctly configured to communicate with each other. This includes network configurations, as well as HugeGraph-specific settings in hugegraph.properties. Misconfigurations here could lead to synchronization issues.

2. Version Compatibility: Double-check that all nodes in your cluster are running the same version of HugeGraph and that they are compatible with any other software components you're using (like your backend database).

3. Backend Database Configuration: Since you're using RocksDB, make sure that it's correctly set up for clustering. RocksDB itself doesn't handle replication or synchronization, so you'll need an external process or tool to manage this. Ensure that your setup correctly replicates data across the instances backing your HugeGraph nodes.

4. Logs and Error Messages: Look for any error messages or warnings in the logs of your HugeGraph server, especially around the time you attempt to create a graph. These messages can provide valuable insights into what might be going wrong.

5. Network Issues: There could be network issues preventing the master node from communicating properly with the other nodes. Check for any firewall rules, network partitioning, or other network-related issues that might be affecting connectivity.

Without more specific error messages or logs, it's challenging to pinpoint the exact cause. I recommend checking the above areas to diagnose the issue further. If you have any error logs or more detailed information, feel free to share them for more targeted assistance.

Remember, the HugeGraph community and documentation are valuable resources that can help guide you through troubleshooting and configuration.

@chenhong1990 U could refer #2512 to try the latest distributed version (With multiple replication and data shards)
