如何排除apache storm worker崩溃的故障
如何排除apache storm worker崩溃的故障
提问于 2019-08-29 07:48:48
我在Apache Storm 1.1.1上运行了一段python代码(通过streamparse)，最近注意到Storm worker不断崩溃。下面是我从worker日志中找到的内容。我想不出什么是罪魁祸首，因为日志没有给我足够的线索。拓扑以前工作得很好。你知道我还能从哪里开始调查吗？

每当我在外部进程螺栓(例如Python螺栓)中看到序列化异常时，我怀疑外部进程正在将某些内容打印到stdout流中。
Storm利用螺栓进程的stdin/stdout进行自己的通信，任何在Python bolts中的记录都应该记录到stderr或一个文件中。
