我想通過windows上的spark提交我的spark-mongo代碼jar。我在獨立模式下使用spark。我在同一臺機器上配置了火花大師和兩名工人。我想用一個師傅和二workers.I我試圖執行以下命令來執行我的jar:spark-submit --master spark://localhost:7077 --deploy-mode cluster --executor-memory 5G --class spark.mongohadoop.testing3 G:\sparkmon1.jar
spark提交java.lang.NullPointerException錯誤
我面臨以下錯誤:

我已經設置winutil在ENV通道。 爲什麼我得到這個錯誤和解決方案是什麼?
是master [standalone master server running?](http://spark.apache.org/docs/latest/spark-standalone.html) - 你有這個錯誤 - 「無法連接到服務器spark://192.168 .242.1:7077" –
