[I] [Bug] hive catalog, Failed to get first split after waiting for 30 seconds. [doris]
ZJHZH opened a new issue, #60682:
URL: https://github.com/apache/doris/issues/60682
### Search before asking
- [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues.
### Version
doris-3.1.4-rc02-7f5ba43de6
### What's Wrong?
If the number of partitions queried exceeds `num_partitions_in_batch_mode`, an error will be reported after waiting for 30 seconds.
```
ERROR 1105 (HY000): errCode = 2, detailMessage = Failed to get first split after waiting for 30 seconds.
```
The `Env.getCurrentEnv().getExtMetaCacheMgr().getScheduleExecutor()` contains a number of threads (greater than `max_external_cache_loader_thread_pool_size` from historical runs) that continuously call `queue.offer` in the `org.apache.doris.datasource.SplitAssignment#appendBatch` method in an infinite loop, the queue is full. It may be due to an abnormal termination of the query, but it is impossible to determine which query terminated or the reason for the termination.
```
private void appendBatch(Multimap<Backend, Split> batch) throws UserException {
for (Backend backend : batch.keySet()) {
// ...
while (needMoreSplit()) {
BlockingQueue<Collection<TScanRangeLocations>> queue =
assignment.computeIfAbsent(backend, be -> new LinkedBlockingQueue<>(10000));
try {
if (queue.offer(locations, 100, TimeUnit.MILLISECONDS)) {
break;
}
} catch (InterruptedException e) {
addUserException(new UserException("Failed to offer batch split by interrupted", e));
}
}
}
}
```
