[GitHub] [druid] Green-Angry-Bird opened a new issue #9469:
NullPointerException in indexer when checking Services from Unified Console
Green-Angry-Bird opened a new issue #9469: NullPointerException in indexer when checking Services from Unified Console
URL: https://github.com/apache/druid/issues/9469
Unified Console throws a 500 when checking Services. In the logs we see a NullPointerException.
### Affected Version
apache-druid-0.17.0
### Description
We are running on single-server/medium
Sometimes (maybe 50% of the time) when checking Services in the Unified Console we get a 500 and see a related NullPointerException in the coordinator-overlord log file.
URL looks like this:
http://DRUID_HOST:8888/unified-console.html#services
Exception looks like this:
