Caideyipi opened a new pull request, #18340: URL: https://github.com/apache/iotdb/pull/18340
## Description Backport #18297 (`834418ed5edc62a10c45f5457a7f94a214eac67e`) to `dev/1.3`. ### Changes - Improve timeout-stage diagnostics and report pending DataNodes. - Introduce `PipeStatus.PRE_DELETE` and make DROP PIPE persist the pre-delete state before notifying DataNodes and removing ConfigNode metadata. - Keep drop-procedure serialization backward compatible. - Prevent heartbeat updates, failure recording, auto-restart, task-agent state changes, and ALTER/START/STOP operations from interfering with a Pipe being dropped. - Adapt the change to the Java 8 and tree-model-only codebase on `dev/1.3`; master-only table-model and new i18n infrastructure are intentionally excluded. ### Verification - [x] Spotless and Checkstyle for `node-commons` and `confignode`. - [x] Reactor compile and test-compile for both modules. - [x] Focused unit tests: `PipeMetaDeSerTest`, `AbstractOperatePipeProcedureV2Test`, `DropPipeProcedureV2Test`, `PipeTaskInfoAutoRestartTest`, `PipeHeartbeatParserTest`, `PipeTableRespTest`, and `ConfigPhysicalPlanSerDeTest` (97 ConfigNode tests plus `PipeMetaDeSerTest`). - [x] `git diff --cached --check` before commit. <hr> This PR has: - [x] been self-reviewed. - [x] added comments explaining the intent of non-obvious compatibility logic. - [x] added or updated unit tests to cover new code paths. <hr> ##### Key changed/added classes (or packages if there are too many classes) in this PR - `AbstractOperatePipeProcedureV2` - `DropPipeProcedureV2` - `PipeTaskInfo` - `PipeHeartbeatParser` - `PipeTaskAgent` - `PipeStatus` -- This is an automated message from the Apache Git Service.
