版本是 2.0.4
我正在使用来自这里的 Cloudera bigtop debian 软件包http://bigtop01.cloudera.org:8080/job/Bigtop-0.6.0-rvs/ws/，但我实际上遇到了从 Apache 镜像获取最新 jar 的相同问题并配置自己。
另外，为了它的价值，我从 Apache 找到了一个 1.1.2 的 debian 包，并且没有这个问题。
所以启动namenode，我得到了这个然后它冻结了。

这很烦人，因为它没有失败，它只是挂起......关于我应该如何调试它的任何想法？
编辑：好的，我很难过。如果我添加 java 选项来侦听 Java 调试器，它可以工作吗？我不明白...
