Review Comment:
   This is our current doc for the underlying commit function
   ```
      * Implementations must throw a {@link 
org.apache.iceberg.exceptions.CommitStateUnknownException}
      * in cases where it cannot be determined if the commit succeeded or 
failed.
      * For example if a network partition causes the confirmation of the 
commit to be lost,
      * the implementation should throw a CommitStateUnknownException. This is 
important because downstream users of
      * this API need to know whether they can clean up the commit or not, if 
the state is unknown then it is not safe
      * to remove any files. All other exceptions will be treated as if the 
commit has failed.
      ```
