[I] [Bug] HiveCatalogLock may experience deadlock [paimon]

sd4324530 opened a new issue, #6782:
URL: https://github.com/apache/paimon/issues/6782

   ### Search before asking
   
   - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.
   
   
   ### Paimon version
   
   1.2.0
   
   ### Compute Engine
   
   flink 1.20.3
   
   ### Minimal reproduce step
   
   This can occur with a small probability during Flink task runtime and is difficult to reproduce.
   
   ### What doesn't meet your expectations?
   
   I've found that when using Flink tasks to write to the Paimon table, there's a chance of a large number of checkpoint failures, and the table gets locked. I'm using object storage OSS, and the error is as follows:

   I guess the problem is here:

   ### Anything else?
   
   _No response_
   
   ### Are you willing to submit a PR?
   
   - [ ] I'm willing to submit a PR!
