我碰到這么幾種情況會導致報上述錯誤:

①flink集群是8085啟動的，但是flink shell的remote模式連接的是8082

所以除了檢查$FLINK_HOME/conf下面的配置，

還要檢查例如~/.bashrc中的諸如下面這種語句:

alias scalaflink="start-scala-shell.sh remote Desktop 8085"

這兩個地方的端口千萬要保持一致.

②前一個flink job提交了沒結束，然后接著提交新job

注意flink shell模式只能在同一時間運行一個job,你必須去web ui上 cancel當前running的job，才能運行下一個．

?
