NiFi正在生成巨大的日志文件-连续日志记录-流控制器执行任务已取消
NiFi正在生成巨大的日志文件-连续日志记录-流控制器执行任务已取消

我的Nifi实例一次又一次地疯狂地生成大量相同的日志。我的流程由ExecuteStreamCommand组成，它在内部调用一个Java excutable jar。另外，看看NiFi UI，该处理器似乎被1个活动线程卡住了。即使当我重新启动NiFi时，这种状态似乎也被保留下来了，而且还会继续发生。正如您在下面看到的，它在一秒钟内记录了数千行相同的日志。太疯狂了！

看起来org.apache.nifi是在调试级别进行日志记录的，这就解释了为什么您会看到这么多日志。默认情况下，NiFi附带的logback.xml记录在INFO级别。
FlowEngine是一个线程池执行器，它执行流的所有任务，您看到的日志记录语句在检查任务完成的结果时发生。您是正确的，当一个处理器被安排在0秒运行时，它会尽可能快地执行，这确实会执行很多任务。我不完全确定为什么有这么多任务被报告为取消而不是正常完成。
