我在localhost中运行了spark，我想使用job spark从三个主题kafka读取数据，我也使用命令行参数从脚本shell执行此作业
/usr/local/spark/bin/spark-submit --class "org.apache.sparkwordcount.SparkCassandra" --master spark://ubuntu:7077 '/home/darif/TestProject/wordcounts/target/wordcounts-1.0-SNAPSHOT.jar' test1 &
/usr/local/spark/bin/spark-submit --class "org.apache.sparkwordcount.SparkCassandra" --master spark://ubuntu:7077 '/home/darif/TestProject/wordcounts/target/wordcounts-1.0-SNAPSHOT.jar' test2 &
/usr/local/spark/bin/spark-submit --class "org.apache.sparkwordcount.SparkCassandra" --master spark://ubuntu:7077 '/home/darif/TestProject/wordcounts/target/wordcounts-1.0-SNAPSHOT.jar' test3 &
但其中只有一个有效，两个已经处于“WAINTING”状态的
你能告诉我这里有什么问题吗？ Thansk
