Question

Я пытаюсь использовать H2O на сервере RHEL 6.7 с R 3.5.0. Вот что происходит, когда я запускаю команду h2o.init() после загрузки пакета с library(h2o):

H2O is not running yet, starting it now...

Note:  In case of errors look at the following log files:
    /tmp/Rtmp0k66FQ/h2o_enrico_started_from_r.out
    /tmp/Rtmp0k66FQ/h2o_enrico_started_from_r.err

Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)

Error in h2o.init() : H2O failed to start, stopping execution.

Стандартный выходной файл журнала показывает ту же информацию вплоть до последнего оператора INFO (т. Е. Без ошибок), а файл журнала ошибок полностью пуст.

Любая помощь в получении этого будет очень признательна! Я использовал H2O в прошлом, и я большой поклонник.

Спасибо!

Оказалось, проблема с прокси. Отключение переменной окружения http_proxy позволяет R правильно подключиться к H2O, т. Е .:

library(h2o)
Sys.unsetenv("http_proxy")
h2o.init()

H2O is not running yet, starting it now...

Note:  In case of errors look at the following log files:
    /tmp/RtmpqEIs7x/h2o_ferreen2_started_from_r.out

На самом деле H2O действительно началось здесь.Сообщение, говорящее об открытии Flow в вашем веб-браузере, является знаком.

Но клиент R не смог связаться с H2O и решил сдаться.

У сообщения внизу есть 504.

Это HTTP-статус 504. Возможно, это порт 54321 брандмауэра RHEL. Вам нужно открыть порт 54321 в брандмауэре.
