apurtell opened a new pull request, #2437: URL: https://github.com/apache/phoenix/pull/2437
When multiple threads register HA URL infos for the same `HAGroupInfo`, `computeIfAbsent()` returns the same HashSet instance to every thread, which then concurrently call `add()` on it. `java.util.HashSet` is not thread-safe. Concurrent `add()` is undefined behavior and can lose entries. -- This is an automated message from the Apache Git Service.
