[GitHub] [druid] kaisun2000 opened a new issue, #13761: Query return not meaningful results with success status when "replicant = 1" when segments are missing
kaisun2000 opened a new issue, #13761:
URL: https://github.com/apache/druid/issues/13761
Please provide a detailed title (e.g. "Broker crashes when using TopN query with Bound filter" instead of just "Broker crashes").
### Affected Version
0.23
### Description
Please include as much detailed information about the problem as possible.
- Cluster size
- Configurations in use
- Steps to reproduce the problem
- The error message or stack traces encountered. Providing more context, such as nearby log messages or even entire logs, can be helpful.
- Any debugging that you have already done
The details are discussed here with @sergioferragut. Basically, a query using simple quantile scanning table (data source) would return NaN as 95th percentile and finished in several millisecond; for the 1st time and 2nd time. Waiting for several minutes and query again, it would return in 10 sec with more meaningful result.
The broker, one historical and finally the coordinator logs are all examined it. It seems this issue happened when 'replicant = 1' and one historical node were lost. And this triggered segment moving across the board. This like trigger NaN query issue.
- 1 broker and 100 historical

I will do a little bit more test to reproduce this issue when I have time.
Ideally we should try to enhance the query to at least return something like no segment are available or how many segment get queries etc.
