ccoffline opened a new issue #4856: URL: https://github.com/apache/incubator-doris/issues/4856
**Describe the bug** ``` errCode = 2, detailMessage = failed to get tablet. tablet_id=18444553, with schema_hash=2071938847, reason=tablet does not exist ``` **To Reproduce** When I delete any file in `be/storage/data` and launch a query, I'll get ``` errCode = 2, detailMessage = failed to initialize storage reader open. tablet=10051.2107108059.d1497902f3afdc62-b351656515255ca8, res=-402, backend=**** ``` So I cannot directly reproduce it. **Troubleshoot** First, `_tablet` gets `nullptr` and comes out this error. https://github.com/apache/incubator-doris/blob/f40868a4805f0ba503bcca9a9c04f704b61c121b/be/src/exec/olap_scanner.cpp#L73-L83 Here `tablet = _get_tablet_unlocked(tablet_id, schema_hash); ` must be `nullptr` and didn't get corrected later. https://github.com/apache/incubator-doris/blob/f40868a4805f0ba503bcca9a9c04f704b61c121b/be/src/olap/tablet_manager.cpp#L582-L610 Here `tablet_map` cannot find the `tablet` https://github.com/apache/incubator-doris/blob/f40868a4805f0ba503bcca9a9c04f704b61c121b/be/src/olap/tablet_manager.cpp#L1409-L1428 I have no idea about when this `_tablet_map_array` will be updated and why can't BE find the tablet. https://github.com/apache/incubator-doris/blob/f40868a4805f0ba503bcca9a9c04f704b61c121b/be/src/olap/tablet_manager.h#L199-L214 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
