我发现太多太多的坑要趟了…

向yarn提交sparkstreaming了，提交脚本以下，使用的是yarn-client

spark-submit --driver-memory 1g --executor-memory 1g --executor-cores 1  --num-executors 3 --class com.yhx.sensor.sparkstreaming.LogicHandle --master yarn-client /opt/spark/SparkStreaming.jar

出现了以下的错误：

其实异常中咱们大概能看出，是监听没法被绑定了…

我这里没法绑定是由于被占用了， 当我终止第一次启动的sparkstreaming后，立刻就开始运行sparkstreaming，这时以前绑定的监听尚未被释放，因此才会出现这个异常。

大概能够使用netstat -anp|grep 端口号  来确认一下…… 

 

唉，尼玛各类坑啊……
