   Thanks for the detailed review. I've addressed all three points in commit 
`ae8128a438`:
   
   1. **Persist and restore the DataVines execution ID**: `executeJob()` now 
calls `setAppIds()` immediately after the execute API returns the execution ID, 
so `AbstractRemoteTask.handle()` persists it. `trackApplicationStatus()` also 
restores `jobExecutionId` from the persisted app ID when the worker recovers, 
and a new test `trackApplicationStatusRestoresExecutionIdFromAppIds` covers the 
recovery path.
   
   2. **Handle all terminal DataVines states**: Added `PAUSE`, `STOP` and 
`NEED_FAULT_TOLERANCE` to the polling switch (matching the DataVines 
`ExecutionStatus` enum), so they no longer fall into the default 
infinite-polling branch. Added parameterized tests for these states.
   
   3. **Fail cancellation when the kill request fails**: 
`RequestUtils.killJobExecution()` now validates the HTTP status and the 
DataVines response and throws on failure; `cancelApplication()` propagates it 
as `TaskException`. The HTTP client also has bounded 
connect/socket/connection-request timeouts. Added tests 
`killJobExecutionInvalidHttpStatusThrowsException` and 
`killJobExecutionInvalidResponseThrowsException`.
   
   Local verification: `mvn -pl 
dolphinscheduler-task-plugin/dolphinscheduler-task-datavines clean test` passes 
(38 tests, 0 failures), and `spotless:check` passes.
