Zookeeper错误连接丢失异常

Question

我在亚马逊EC2实例上运行SeqWare VM我试图使用SeqWare查询引擎从VCF文件查询数据。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。它总是返回下面的错误。我查看了进程，发现没有任何所需的节点正在运行，因此我登录到根目录并进入etc/init.d目录并重新开始一切，此时，当T尝试导入数据时，我甚至没有错误，我必须停止这个过程。

Answer 1

我想它out.The阿帕奇服务是从Cloudera的软件包安装。当实例重新启动时，他们没有重新启动，显然，从etc/init.d运行它们的脚本是不正确的方法。我发现这些命令可以在cloudera文档中重新启动它们。

Answer 2

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