can not read realtime data when using indexer process instead of middleManager peon process to ingest metrics from kafka #10538

Hi @quenlang, I haven't heard of any issues so far, so want to narrow down the scope of potential issue. Can you check the result of the |
Hi @jihoonson, as you say, the response of 0.18.1 includes the indexer node, but 0.19.0 doesn't. the response of the same query in 0.18.1:

Thanks. I think maybe something was broken in #9971, but not 100% sure yet. I will dig into it more. |
@jihoonson - We are also experiencing the same issue after upgrading two of our clusters to 0.19. Our temporary solution was to downgrade our indexers to 0.18.1, inspired by this issue: #10258. I'm curious if there's an ETA for fixing this? It's kind of a big deal for our users. I know indexers are experimental, do you think we should revert to using middle managers and peons for the stability? |
#10631 should fix this. |
Closing as #10631 is merged. Please feel free to reopen if you still see the same issue. |
Hi, all
Affected Version
0.19.0 and 0.20.0
Description
I found that can not query real-time data when using the indexer process instead of the peon process to ingest metrics from the Kafka topic.
Then I terminated the ingestion task, the segments handoff to HDFS and the historical nodes cached the segments, it is queryable.
I downgraded to 0.18.1 but didn't meet this problem, it worked fine.
I think this is a bug after 0.18.1. Any suggestions? @jihoonson
Thanks a lot!
