barking-code opened a new pull request, #3357:
URL: https://github.com/apache/iceberg-python/pull/3357

   Related: #1744, #1747, #1941
   
   # Rationale for this change
   
   #1747 / #1941 caught the `TSaslClientTransport` reopen failure on the client 
side, but the doomed `open()` attempt still completes a TCP handshake before 
aborting, which leaves a `TTransportException` event in the HMS server log per 
`_HiveClient` re-entry. In production this produces a steady stream of 
server-side error events matched by HMS alert filters.
   
   `TSaslClientTransport` is single-use by design (its `SASLClient` is disposed 
on `close()` and has no reset). Reusing it across context-manager entries was 
the original misuse. This PR makes the transport single-use: 
`_HiveClient.__init__` no longer creates a transport, `__enter__` creates and 
opens a fresh one, `__exit__` closes it. The `try/except` retry from #1747 / 
#1941 is removed because the failure it protected against cannot occur on a 
fresh transport.
   
   `_HiveClient` itself stays long-lived, so `HiveCatalog` callers see no 
behaviour change.
   
   # Are these changes tested?
   
   - New unit test asserts that the transport instance differs between two 
consecutive context-manager entries
   - Existing `test_create_hive_client_with_kerberos_using_context_manager` 
continues to pass
   - Empirical verification against a Kerberized HMS (Hive 3.1.0): before → 29 
server-side `TTransportException` events per 30 re-entries, after → 0
   
   # Are there any user-facing changes?
   
   No.
