【问题描述】:
我使用以下命令运行了wordcount的spark java示例:-
time spark-submit --deploy-mode cluster --master spark://192.168.0.7:6066 --class org.apache.spark.examples.JavaWordCount /home/pi/Desktop/example/new/target/javaword.jar /books_50.txt
当我运行它时,输出如下:-
Running Spark using the REST application submission protocol.
16/07/18 03:55:41 INFO rest.RestSubmissionClient: Submitting a request to launch an application in spark://192.168.0.7:6066.

}
我检查了特定工人 (192.168.0.12) 的日志,它说:-

我的 spark-env.sh 文件(用于 master)包含:-
export SPARK_MASTER_WEBUI_PORT="8080"
export SPARK_MASTER_IP="192.168.0.7"
export SPARK_EXECUTOR_MEMORY="10M"
我的 spark-env.sh 文件(用于工人)包含:-
export SPARK_WORKER_WEBUI_PORT="8080"

请帮忙...!!

您曾在哪里解决过这个问题?我在 spark v2.0.0 上遇到了完全相同的问题。

您好,我无法为这个特定问题找到任何线索。因此,我开始为 wordcount 流式传输 python 示例。如果您找到解决方法,请告诉我。
