Я пытаюсь выполнить spark-shell на Windows 10, но я все время получаю эту ошибку каждый раз, когда запускаю ее.Почему искр-оболочка терпит неудачу с NullPointerException?
Я использовал как последние версии, так и искро-1.5.0-bin-hadoop2.4.

Я загрузил искру-1.5.0-bin-hadoop2.4 и начал искру-оболочку, но sqlContext загружает без проблем для меня. Я получил те же предупреждающие сообщения **, кроме ** для предупреждения имени хоста, поэтому я предполагаю, что вам нужно будет исправить сетевую конфигурацию. –
Я не могу понять причину. Я играл с заранее подготовленным пакетом. После того, как я попытался загрузить исходный код 'git clone git: //github.com/apache/spark.git -b branch-1.6', он сработал. – Habib
@Habib Thx. Я тоже играю с готовым пакетом. Какую ОС вы используете, кстати? – mbh86
