[GitHub] [druid] kfaraz opened a new pull request, #13980: Handle missing server in BrokerServerView
kfaraz opened a new pull request, #13980:
URL: https://github.com/apache/druid/pull/13980
Due to race conditions, the `BrokerServerView` may sometimes try to add a segment to a server which has already been removed from the inventory. This results in an NPE and keeps the `BrokerServerView` from processing all change requests.
Changes:
- Handle null values returned by the backing inventory view in `BrokerServerView`
- Minor refactor in `HttpServerInventoryView` for cleanup
