我在长期运行的Spark Streaming应用程序中获得以下异常。异常可能在几分钟后发生，但也可能不会发生几天。这是非常一致的输入数据。
我见过this Jira ticket，但我不认为这是同一个问题。这是java.lang.IllegalArgumentException，这是java.io.IOException: Class not found。
我的应用程序是流数据并使用Spark SQL写入Parquet。
我正在使用Spark 1.5.2。有什么想法吗？

答案 0 :(得分：3)
我将回答我自己的问题。我认为这会在您启动流式应用程序然后删除或替换spark-submit中使用的jar文件时发生。很可能正在运行的JVM Spark Driver应用程序尝试从不再存在或已被替换的jar文件中加载某些类。
我不知道这是真的，但我对这个问题感兴趣，所以我认为发表我目前的想法是好的。
