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

Кажется разобрался, включил DEBUG режим и получил ошибку "no master is set despite of join request". Погуглил, оказалось что это связано с тем что набор плагинов на хостах не идентичен, скопировал плагины на новую ноду - всё ок. Спасибо.
