Yerel modda sorunsuz çalışan bir Spark uygulamam var, ancak Spark kümesine gönderirken bazı sorunlar yaşıyorum.
Hata mesajı aşağıdaki gibidir:

Yukarıdaki kodda GroupEvolutionES
ana sınıftır. Hata mesajı "Yapılandırmanızda bir ana URL ayarlanmalıdır" diyor, ancak "--master" parametresini için sağladım spark-submit
.
Bu sorunu nasıl çözeceğini bilen var mı?
Spark sürümü: 1.6.1
