dear:

i am run spark streaming application in yarn-cluster and run 17.5 hour application killed and throw Exception.

 

User class threw exception: org.apache.spark.SparkException: Job aborted due to stage failure: ShuffleMapStage 4896 (foreachRDD at SparkStreamingApp.scala:73) has failed the maximum allowable number of times: 4. Most recent failure reason: org.apache.spark.shuffle.FetchFailedException: Unable to create Channel from class class io.netty.channel.socket.nio.NioSocketChannel
