YongGang commented on PR #14443:
URL: https://github.com/apache/druid/pull/14443#issuecomment-1606235269
I rebased from master again hope to fix the IT (ITNestedQueryPushDownTest)

Although the error said failed to get leader, I couldn't think of a way this
PR caused this as the `ServiceStatusMonitor` has been registered to run.
