> Key: IMPALA-14267
> URL: https://issues.apache.org/jira/browse/IMPALA-14267
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Yida Wu
> Assignee: Yida Wu
> Priority: Major
> Labels: admission-control

> When the admissiond is at capacity, often due to long-running queries or queries that cannot be canceled properly, newly queued queries may not be dequeued. In such cases, excessive log messages are repeatedly printed each time dequeuing fails. This can result in a large volume of redundant logs that provide limited diagnostic value.
> It would be better to improve this by reducing the frequency of these logs, especially when the condition could last a long time.
