Добрый день! Есть работающий кластер на 1.5.2, состоящий их 2х нод на CentOS6. Нужно без простоя перевести их на CentOS7, поэтому решил добавить 2 новые ноды в кластер, и впоследствии отключить старые. Поставил на новые ноды Эластик такой же версии, Java такой же версии, при запуске новой ноды получаю такое в логах:

Оба существующих мастера c новой ноды доступны, но идёт постоянный relocating shards
