SparkStreaming+Flume出现ERROR ReceiverTracker: Deregistered receiver for stream 0: Error starting receiver 0 - org.jboss.netty.channel.ChannelException

我发现太多太多的坑要趟了…

向yarn提交sparkstreaming了，提交脚本如下，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

出现了如下的错误：

其实异常中我们大概能看出，是监听无法被绑定了…

我这里无法绑定是因为被占用了， 当我终止第一次启动的sparkstreaming后，马上就开始运行sparkstreaming，这时之前绑定的监听还没有被释放，所以才会出现这个异常。

大概可以使用netstat -anp|grep 端口号  来确认一下…… 

 

唉，尼玛各种坑啊……
