## Description `IdealState.getInstanceStateMap(partitionName)` can return `null` when a partition exists in the ideal-state partition set but has no instance assignments yet. Two call-sites in `BaseServerStarter` dereference this result directly to check for `CONSUMING` state: 1. `registerServiceStatusHandler` (line ~413) — iterates all realtime resources on server startup 2. `getConsumingSegments` (line ~477) — called to find consuming segments for a realtime table Both cause a `NullPointerException` in transient cluster states (e.g. during reassignment or partial setup). **Fix:** guard both call-sites with a null check before accessing the instance state, consistent with how the same pattern is handled in `ShowClusterInfoCommand` and `ZKOperator`. ## Related Same family of fixes as #18697 (DebugResource), #18455 (HelixHelper), and the lead-controller EV fix. -- This is an automated message from the Apache Git Service.
