virtualbox - 在 VirtualBox VM 之外无法访问 Accumulo 概览控制台

Question

我在 Ubuntu 12.04 VirtualBox VM 中运行 Accumulo 1.5。我已将 accumulo-site.xml instance.zookeeper.host 文件设置为 VM 的 IP 地址，我可以连接到 accumulo 并从远程客户端计算机运行查询。在客户端机器上，我还可以使用浏览器查看 hadoop NameNode、浏览文件系统等。但是除了直接从 Accumulo VM 之外，我无法从其他任何地方连接到 Accumulo 概述页面(端口 50095)。虚拟机和客户端之间没有防火墙，除了无法访问 Accumulo 概述页面之外，其他一切似乎都运行良好。

是否需要更改配置设置以允许外部访问 Accumulo 概述控制台？

谢谢

通过手动应用此补丁，我能够让 Accumulo 监视器绑定(bind)到所有网络接口(interface):
https://git-wip-us.apache.org/repos/asf?p=accumulo.git;a=commit;h=7655de68

在 conf/accumulo-env.sh添加:

# Should the monitor bind to all network interfaces -- default: false
export ACCUMULO_MONITOR_BIND_ALL="true"

在 bin/config.sh添加:

# ACCUMULO-1985 provide a way to use the scripts and still bind to all network interfaces
export ACCUMULO_MONITOR_BIND_ALL=${ACCUMULO_MONITOR_BIND_ALL:-"false"}

并修改 bin/start-server.sh匹配:

SOURCE="${BASH_SOURCE[0]}"
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a symlink
   bin="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
   SOURCE="$(readlink "$SOURCE")"
   [[ $SOURCE != /* ]] && SOURCE="$bin/$SOURCE" # if $SOURCE was a relative symlink, we need to resolve it relative to the path where the symlink file was located
done
bin="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
# Stop: Resolve Script Directory
