我在亚马逊EC2实例上运行SeqWare VM我正在尝试使用SeqWare查询引擎从VCF文件中查询数据。当我第一次启动实例并按照说明导入数据时，它工作正常，并继续工作，直到我停止实例。当我重新启动它。它不会让我导入任何东西，也不会创建新的工作区。它总是返回以下错误。我查看了进程，发现所有必需的节点都没有运行，所以我登录到root并转到etc/init.d目录并再次启动所有内容，此时，当T尝试导入数据时，我不知道甚至得到一个错误，我必须停止这个过程。

我弄清楚了。从cloudera包中安装了apache服务。当实例重新启动时，它们没有被重新启动，显然，只是从etc / init.d运行它们的脚本是不正确的方法。我在cloudera文档中找到了重启它们的命令。

我也遇到了这个问题。我可以通过在启动zookeeper时提供jute.maxbuffer参数来解决这个问题。
