java - 启动 Apache Storm Supervisor 时出错

Question

我正在尝试重新启动 Apache Storm 集群，但遇到了一些问题。我有两个不会重新启动的主管。当我查看主管日志时，我看到以下错误:

我猜测此错误与分配给主管的数据现在已损坏有关。处理损坏数据的最佳方法是什么？我是 Storm 的新手，只了解它的基本信息。

Storm 0.9.3 Java - IBM J9 VM(内部版本 2.7，JRE 1.7.0 Linux PPC64-64)

Answer 1

所以worker目录下有文件。这些文件已损坏，我必须删除 worker 目录下的所有内容。然后我重新启动了主管，这又开始工作了。
